Chrissy Teigen Is Nude For GQ Magazine (PHOTO)

Chrissy Teigen is a free spirit who rarely seems to hold anything back.

That's why it comes as no surprise that the 27-year-old model didn't let a little thing like clothing come between her and the camera for her GQ photo shoot.

Teigen posed completely nude for the magazine (save for a pair of Marc Jacobs heels), and was totally game to offer readers some dating advice -- she's engaged to John Legend, so we'd say she knows what she's talking about.

Though it's Teigen's Sports Illustrated bikini photos that made her famous, it's her Twitter account that keeps people talking about her -- and she admits she sometimes wishes she thought before she typed:

"All the time! But not really a regret that I thought it, just that I said it," she told GQ, explaining that the nude photo she shared on Instagram in March is a prime example. "My naked-spray-tan thing comes to mind. What no one knows is that my mom took it! My mom frickin' threw me under the bus!"

3 die in floods, 75,000 forced from Calgary homes

CALGARY, Alberta (AP) ? At least three people were killed by floodwaters that devastated much of southern Alberta, leading authorities to evacuate the western Canadian city of Calgary's entire downtown. Inside the city's hockey arena, the waters reached as high as the 10th row.

Canadian Prime Minister Stephen Harper called the level of flooding "stunning" and said officials don't know yet if it will get worse, but said the water has peaked and stabilized and noted that the weather has improved.

Overflowing rivers washed out roads and bridges, soaked homes and turned streets into dirt-brown waterways around southern Alberta. Royal Canadian Mounted Police Sgt. Patricia Neely said two bodies were recovered and third was in an area that made it too dangerous to recover.

As the sun rose in Calgary on Saturday morning it wasn't raining. Some of the 75,000 flood evacuees were holding out hope they might soon be allowed back into their homes. However, Mayor Naheed Nenshi said earlier the downtown area was still without power and remained off limit. "It is extremely unlikely that people will be able to return to those buildings before the middle of next week," he said.

Nenshi also warned there could be another wave of danger ahead.

"There is a scenario in which upstream events at the dams further upstream from the city will lead to another surge in the Bow River," he said. "We don't know how realistic that scenario is, but we will have some hours warning if that actually happens."

The flood has hit some of the city's iconic structures hard. The Saddledome, home to the National Hockey League's Calgary Flames, was flooded up to the 10th row. That would mean the dressing rooms are submerged as well.

Harper, a Calgary resident, said he never imagined there would be a flood of this magnitude in this part of Canada.

"This is incredible. I've seen a little bit of flooding in Calgary before. I don't think any of us have seen anything like this before. The magnitude is just extraordinary," he said.

"We're all very concerned that if gets much more than this it could have real impact on infrastructure and other services longer term, so we're hoping things will subside a bit."

Twenty-five neighborhoods in the city, with an estimated 75,000 residents, were evacuated due to floodwaters in Calgary, a city of more than a million people that hosted the 1988 Winter Olympics and is the center of Canada's oil industry. About 1,500 have gone to emergency shelters while the rest have found shelter with family or friends, Nenshi said.

About 350,000 people work in downtown Calgary on a typical day. However, officials said very few people need to be moved out, since many heeded warnings and did not go to work Friday.

Alberta Premier Alison Redford said Medicine Hat, downstream from Calgary, was under a mandatory evacuation order affecting 10,000 residents. The premier warned that communities downstream of Calgary had not yet felt the full force of the floodwater.

A spokesman for Canada's defense minister said 1,300 soldiers from a base in Edmonton were being deployed to the flood zone.

Police were asking residents who were forced to leave the nearby High River area to register at evacuation shelter. The Town of High River remained under a mandatory evacuation order.

The flood was forcing emergency plans at the Calgary Zoo, which is situated on an island near where the Elbow and Bow rivers meet. Lions and tigers were being prepared for transfer, if necessary, to prisoner holding cells at the courthouse.

Schools and court trials were canceled Friday and residents urged to avoid downtown. Transit service in the core was shut down.

Residents were left to wander and wade through streets waist-deep in water.

Newlyweds Scott and Marilyn Crowson were ordered out of their central Calgary condominium late Friday as rising waters filled their parking garage and ruptured a nearby gas line. "That's just one building but every building is like this," he said. "For the most part, people are taking it in stride."

Crowson, a kayaker, estimated the Bow River, usually about four feet deep, is running at a depth of 15 feet (4.57 meters).

"It's moving very, very fast," he said of the normally placid stream spanned by now-closed bridges. "I've never seen it so big and so high."

It had been a rainy week throughout much of Alberta, but on Thursday the Bow River Basin was battered with up to four inches (100 millimeters) of rain. Environment Canada's forecast called for more rain in the area, but in much smaller amounts.

Calgary was not alone in its weather-related woes. Flashpoints of chaos spread from towns in the Rockies south to Lethbridge.

Helena Bonham Carter Joins Kenneth Branagh's Cinderella

AP

It's hard to imagine Helena Bonham Carter starring in anything but a fantasy or period piece, or a cross-over of the two.

Disney revealed today that our favorite female Death Eater will once again flick a wand, but this time using magic for good as the fairy godmother in the upcoming live-action "Cinderella." Kenneth Branagh's adaptation of the classic fairy tale will also star Lily James of "Downton Abbey" in the title role, an evil Cate Blanchette as the wicked stepmother, and Richard Madden of "Games of Thrones" as Prince Charming.

Bonham Carter seems a perfect fit for the role, having been cast as one bizarre, fantastical character after another -- from the Red Queen to Bellatrix Lestrange to Mrs. Lovett. Yet we wonder if she will ever tone things down and return to her simpler roots, ? la Marla Singer.

No release date for the "Cinderella" reboot has been announced yet, but filming is reported to begin this fall in London.

  • ?Cinderella II and III? (2002)

    Fifty-two years after Cinderella lost her glass slipper, Disney released the first of two sequels to the romance classic. In 2002?s "Cinderella II: Dreams Come True," Jaq the mouse is turned into Cinderella?s human pageboy and one of her evil stepsisters falls in love with a low-class man. In "Cinderella III: A Twist in Time," from 2008, Cinderella?s wicked stepmother gets ahold of the Fairy Godmother?s wand and goes back in time to when Cinderella tried on the slipper (uh oh).

  • ?Pocahontas II: Journey to a New World? (1998)

    Disney has a poor track record of re-telling American history, so why not make a ?Pocahontas? sequel and continue to get her story wrong? The follow up to the 1995 movie tells a Disney-friendly version of Pocahontas?s life in England and how she meets and marries John Rolfe (a tobacco farmer in real life, but diplomat in the movie). The movie ends with John Smith confessing his love to Pocahontas (in real life, he betrayed his promise to her and her father), and Pocahontas sailing off happily with husband Rolfe (in real life, she died soon after). Disney always has to romanticize everything -- and confuse the heck out of kids.

  • ?Return to Never Land? (2002)

    Although many ?Peter Pan? live-action reboots and sort-of sequels have been made by other studios, Disney decided to go back to Neverland themselves in 2002. This theatrically released follow-up takes place during World War II, as Wendy?s daughter Jane is kidnapped by Captain Hook. Surprisingly, this film actually opened in third place.

  • ?Mulan II? (2005)

    Things ended just fine in 1998?s ?Mulan? when the titular character returned home and Li Shang stayed for dinner. But Disney had to keep going of course, and in the movie?s 2004 sequel Li Shang finally asks Mulan to marry him. The film follows the couple as they escort the Emperor's daughters to meet their new fiances. While described as a continuation of the first film?s ?epic adventure,? after fighting the Huns, everything else seems utterly boring.

  • ?The Jungle Book 2? (2003)

    ?The Jungle Book 2? is one of the very few Disney sequels to be released theatrically before going to video, most likely because it features the voices of Haley Joel Osment and John Goodman. In this movie, Mowgli returns to the jungle -- but nothing really happens, as he ends up back in the Man Village at the end anyway (well, that was pointless).

  • ?Bambi II? (2006)

    Sixty-four years after the 1942 classic, Disney returned to the sad motherless deer in the woods. The sequel (or, technically, midquel) takes place during the gap of time in the original, after Bambi?s death and before he grows up. While the film was a direct-to-video release in most countries, it was -- oddly enough -- theatrically released in Argentina.

  • ?An Extremely Goofy Movie? (2000)

    We all remember 1995?s ?A Goofy Movie? where Max is forced to go on a chaotic road trip with his father. As if Goofy didn?t embarrass Max enough in the first movie, this time he goes way too far. After Max heads to college, Goofy loses his job and must return to school to finish up his degree. Obviously, he enrolls at his son?s school. No one wants their college fun spoiled by dad.

  • ?Stitch! The Movie? and More ?Lilo & Stitch? Sequels

    ?Lilo & Stitch? became a giant franchise after the original 2002 film. The sequels first kicked off with 2003?s direct-to-video ?Stitch! The Movie,? followed by a spin-off TV series, then direct-to-video ?Lilo & Stitch 2: Stitch Has a Glitch? in 2005, and finally 2006?s ?Leroy & Stitch." Who knew the little blue alien would prove to be so popular?

  • ?The Return of Jafar? and More ?Aladdin? Sequels

    That?s right -- Disney ventured back into Aladdin?s Arabian Nights adventures twice, including ?The Return of Jafar? in 1994 and ?Aladdin and the King of Thieves? in 1996. Although Robin Williams didn?t voice the Genie in the first sequel due a contract dispute with Disney, he returned as our favorite wish-granter in ?King of Thieves.?

  • ?Beauty and the Beast: The Enchanted Christmas? and More Sequels

    Belle and the Beast return twice in both "Beauty and the Beast: The Enchanted Christmas" in 1997 and "Beauty and the Beast: Belle's Magical World" in 1998, both of which went straight to video. In the Christmas movie, the Beast turns into a Scrooge by not wanting to celebrate the holiday. The second sequel tells a series of stories each with a different moral. Who better to learn life lessons from than a bunch of humans turned into objects for their bad deeds?

  • ?The Little Mermaid II? and Prequel

    Poor Ariel finally escaped the terrors of the sea in the 1989 classic film, but Disney just had to toss her back in with the fish. In 2000?s ?The Little Mermaid II: Return to Sea,? Ariel and Eric?s daughter swims into some dark waters and gets tangled up with Morgana, Ursula?s sister. But that wasn?t enough so Disney dove back in with ?The Little Mermaid: Ariel?s Beginning? in 2008 to recount the origin story of the young mermaid.

  • ?Lady and the Tramp II: Scamp's Adventure? (2001)

    The 1955 classic about puppy love gets dug up again in Disney?s 2001 sequel, which follows Lady and Tramp?s only son pup Scamp. To no one's surprise, Scamp turns out to be more like his father. In the film, he runs away from his family to be a wild dog and join a gang of junkyard dogs. Sometimes you can?t take the mutt out of the pup.

  • ?101 Dalmatians II: Patch's London Adventure? (2003)

    You probably remember Disney?s live-action remake and sequel of ?101 Dalmatians."?As if those both weren't enough they decided to make an animated sequel as well. "101 Dalmatians II: Patch's London Adventure" follows Patch, one of the pups, who gets left behind on his family?s moving day.

Obama expected to pick James Comey as next FBI chief: source

By Steve Holland

WASHINGTON (Reuters) - President Barack Obama is expected to nominate former Justice Department official James Comey as his next head of the FBI, a source said on Wednesday.

If confirmed by the Senate, Comey, a Republican, would replace FBI Director Robert Mueller, who has led the agency since just before the September 11, 2001, attacks. Mueller is expected to step down this fall.

The White House would not comment on Obama's decision but the source said Obama had been leaning toward Comey in recent days. It was unclear when an announcement would be made.

White House homeland security adviser Lisa Monaco, who emerged as an instrumental aide to Obama during the Boston Marathon bombings last month, also had been under consideration.

Comey, 52, served as deputy U.S. attorney general for President George W. Bush. He had previously been the U.S. attorney for the Southern District of New York.

In an earlier post as assistant U.S. attorney for the Eastern District of Virginia, Comey handled the Khobar Towers bombing case that arose out of an attack on a U.S. military facility in Saudi Arabia in 1996. Seventeen U.S. military members died in the attack.

Comey gained notoriety for refusing in 2004 to certify the legal aspects of National Security Agency domestic surveillance during a stint as acting attorney general while John Ashcroft was hospitalized with pancreatitis.

That refusal prompted senior White House officials, counsel Alberto Gonzales and chief of staff Andrew Card, to try to persuade Ashcroft to sign the certification. Comey, who was in the room, said Ashcroft refused.

Comey later told the Senate Judiciary Committee at a 2007 hearing that the situation was "probably the most difficult night of my professional life." His actions endeared him to many Democrats opposed to the Bush's domestic surveillance program.

After leaving the Justice Department in 2005, Comey was general counsel to aerospace giant Lockheed Martin until 2010.

Comey most recently joined Columbia University's law school as a senior research scholar after working for Bridgewater Associates, an investment fund, from 2010 to 2013. He was general counsel for aerospace giant Lockheed Martin from 2005 to 2010.

How to frustrate a quantum magnet: 16 atomic ions simulate a quantum antiferromagnet

May 3, 2013 ? Frustration crops up throughout nature when conflicting constraints on a physical system compete with one another. The way nature resolves these conflicts often leads to exotic phases of matter that are poorly understood. This week's issue of Science Magazine features new results from the research group of Christopher Monroe at the JQI, where they explored how to frustrate a quantum magnet composed of sixteen atomic ions -- to date the largest ensemble of qubits to perform a simulation of quantum matter.

Originating in large part with Richard Feynman's 1982 proposal, quantum simulation has evolved into a field where scientists use a controllable quantum system to study a second, less experimentally feasible quantum phenomenon. In short, a full-scale quantum computer does not yet exist and classical computers often cannot solve quantum problems, thus a "quantum simulator" presents an attractive alternative for gaining insight into the behaviors of complex material. Says Monroe, "With just 30 or so qubits, we should be able to study ordering and dynamics of this many-body system that cannot be predicted using conventional computers. In the future, make that a few hundred qubits and there's simply not enough room in the universe for all the memory required to do the calculation."

In this experiment, JQI physicists engineer a quantum magnet using lasers and ion qubits. The ion trap platform has long been a leader in the field of quantum information and is an ideal playground for quantum simulations (see image 1 in gallery of ion trap used here). Ions are charged particles that interact strongly via the Coulomb force, which is an attraction/repulsion that decreases as particles separate. When a handful of positively charged ytterbium ions are thrown together, they repel each other, and, for this oblong ion trap, form a linear crystal (see gallery image 2 of real camera images of single ions arranged in a crystal). Each ion has two internal energy states that make up a qubit.

Laser beams can manipulate the Coulomb force to create tunable, long range magnetic-like interactions, where each ion qubit represents a tiny magnet*. Imagine that invisible springs connect the ions together. Vibrations occurring on one side of the crystal affect the entire crystal. This is called collective motion and is harnessed to generate a force that depends on how a magnet is oriented (which state the qubit is in). The team can program this state-dependent force by simultaneously applying multiple laser beams, whose colors (frequencies) are specially chosen with respect to the internal vibrations of the ion crystal. The amount of influence each magnet has on the rest of the chain primarily depends on the choice of laser frequencies. The crystal geometry has little to do with the interactions. In fact, for some laser configurations the ions that are farthest apart in space interact most strongly.

Phenomena due to this type of magnet-magnet interaction alone can be explained without quantum physics. An additional uniform magnetic field, (here created with yet another laser beam), is necessary for introducing quantum phase transitions and entanglement. This added magnetic field (oriented perpendicular to the direction of the interactions) induces quantum fluctuations that can drive the system into different energy levels.

In the experiment, the long-range ion-ion interaction and a large effective magnetic field are turned on simultaneously. In the beginning of the simulation the ion magnets are oriented along the direction of the effective magnetic field. In the quantum world, if a magnet is pointing along some direction with certainty, its magnetic state along any perpendicular direction is totally random. Hence the system is in a disordered state along the perpendicular direction of magnetic [spin] interactions.

During the quantum simulation the magnetic field is reduced and the ion crystal goes from being in this disordered state, with each ion magnet pointing along a random direction, to being determined by the form of the magnetic interactions. For some cases of antiferromagnetic (AFM) interactions, the spins will end in a simple up-down-up-down-etc. configuration. With the turn of some knobs, the team can cause the AFM interactions to instead frustrate the crystal. For example, nearest neighbor AFM interactions can compete strongly with the next-nearest neighbor interactions and even the next-next-nearest neighbor constraints. The crystal can easily form various antiferromagnetic combinations, instead of the simple nearest neighbor antiferromagnet (up down up down). In fact, with a few technical upgrades, the researchers can potentially engineer situations where the magnets can reside in an exponentially large number of antiferromagnetic states, generating massive quantum entanglement that accompanies this frustration.

Previously, this same group of researchers performed quantum simulations of a ferromagnet (all magnets oriented same direction) and of the smallest system exhibiting frustration. Their ability to utilize the collective motion allows them to explore different facets of quantum magnetism. The team can 'at will' modify how the different collective modes contribute to magnetic order by merely changing the laser colors and/or the ion separation. This new work demonstrates the versatility of their system, even as particles are added. As lead author Dr. Rajibul Islam explains "We have a knob that adjusts the range of the interaction, something that is unavailable in real materials. This type of simulation could therefore help in the design of new types of materials that possess exotic properties, with potential applications to electrical transport, sensors, or transducers."

*Physicists use mathematical spin models, such as the Ising model studied here, to understand quantum magnets, thus in this news article, for clarity the ions are called "magnets." In the language of the Science Magazine article, they are called "spins."

Frequency Information

This experiment is all about frequency. The ions themselves are vibrating at a frequency determined by an electrostatic trap--about 1 MHz or 1 million vibrations/second. The ion qubit is made from two internal energy levels that are separated in frequency by about 12 GHz or 12 billion vibrations/second (microwave domain). When radiation with a frequency that matches either of these frequencies shines onto the ion, then the radiation is said to be in resonance with that transition. For example, 12 GHz microwave radiation will make the ion qubit cycle between two internal states. If MHz radiation is coupled to the ion, it will begin vibrating. In the quantum regime, the quanta of vibration called a phonon can be controllably added and removed from the system. These phonons act as communication channels for the magnets, and are instrumental in generating rich varieties of interactions.

Scientists must be clever about generating frequencies. We are constantly being bathed in radiation from cellphones (GHz), infrared (terahertz or 1000 GHz), UV radiation (petahertz or 1 million GHz), and more--much of this goes unnoticed. The ion here is sensitive to only very precise frequencies. To get that qubit to flip flop between two qubit states, they need to apply a radiation at precisely 12.642819 GHz. To create spin-spin interactions, they also need to simultaneously excite its motion--it is vibrating at a frequency that is 10,000 times smaller. Lasers are the key--here at 369 nm, just barely in the ultraviolet regime. Previously, a JQI news item described how they can use a pulsed laser to generate 12.642819 GHz. Scientists control the frequency, power and the direction of light waves very precisely by hitting the laser beams with sound waves and oscillating electric fields (in devices such as the acousto- and electro-optic modulators). These devices act to add lower frequencies necessary for exciting the motion in the trap as well as fine tune the main laser beam to address certain atomic transitions. This method, called modulation, is versatile and is one of the key features that make this and other quantum physics experiments possible.
