Harvard physicists have expanded the possibilities for quantum engineering of novel materials such as high-temperature superconductors by coaxing ultracold atoms trapped in an optical lattice — a light crystal — to self-organize into a magnet, using only the minute disturbances resulting from quantum mechanics. The research, published in the journal Nature, is the first demonstration of such a “quantum magnet” in an optical lattice.As modern technology depends more and more on materials with exotic quantum mechanical properties, researchers are coming up against a natural barrier.“The problem is that what makes these materials useful often makes them extremely difficult to design,”said senior author Markus Greiner, an associate professor in Harvard’s Department of Physics. “They can become entangled, existing in multiple configurations at the same time. This hallmark of quantum mechanics is difficult for normal computers to represent, so we had to take another approach.”That approach is using a so-called “quantum simulator” — the properties of a quantum material are simulated with an artificial quantum system that can behave similarly, but that is easier to manipulate and observe.The physicists found that when they applied a force to a crystal formed by ultracold atoms trapped in an optical lattice, a Mott insulator, the atoms behaved like a chain of little magnets that repelled one another, in the presence of an external magnetic field that sought to align them.“When the external magnetic field was strong, all of the magnets aligned to it, forming a paramagnet,” said co-author Jonathan Simon, a postdoctoral fellow in physics. “When we reduced the magnetic field, the magnets spontaneously anti-aligned to their neighbors, producing an antiferromagnet.”While such self-organization is common in everyday materials, it typically depends on temperature to jostle the system into the new order, like shaking a Boggle game to help the dice settle, the researchers say. “But the temperature was so low that thermal fluctuations were absent,” explained Simon. “Our fluctuations arose from quantum mechanics.”When quantum mechanics takes over, things get bizarre. “Quantum fluctuations can make the magnets point in multiple directions simultaneously,” Greiner said. “This ‘quantum weirdness’ gives rise to many of the fascinating properties of quantum magnets.”Greiner and his colleagues used a quantum gas microscope to observe individual magnets at temperatures of one billionth of a degree above absolute zero (-273 Celsius). They were able to watch as quantum fluctuations flipped the magnets around, turning a paramagnet into an antiferromagnet and back again.“Observing quantum magnetism in a cold gas is a crucial first step toward quantum simulation of real magnetic materials,” Greiner said. “There remain many exciting questions to answer, and we have only just scratched the surface. By studying the bizarre and wonderful ways that quantum mechanics works, we open new perspectives not only for developing novel high-tech materials, but also for quantum information processing and computation.”Greiner and Simon’s co-authors are Waseem Bakr, Ruichao Ma, Eric Tai, and Philipp Preiss, all in the University’s Physics Department. Their work was supported by the Army Research Office through the DARPA OLE program, the Air Force Office of Scientific Research MURI program, and by grants from the National Science Foundation (NSF).

Especially the “you might be a redneck” bits. Sure, they sometimes hit a bit close to home, but I always thought it was healthy to laugh at yourself every so often.I’m a firm believer that every segment of society should be able to poke fun at itself. I was trained as a lawyer. There’s a ton of low hanging fruit there if you ever need a laugh. Believe me. But this blog is about management. So with a hat tip to Mr. Foxworthy, here goes.If someone asks you how your train ride was, and you respond, “Fantastic! I knocked out about 200 emails,”….you might be a manager.If you have four business books sitting on your nightstand…you might be a manager.If the fact that you haven’t picked up a one of those four business books in a week bothers you…you might be a manager.If you have more “productivity” apps on your phone than games…you might be a manager.If someone asks you who your favorite author is, and Jim Collins comes to mind…You might be a manager. If you compare notes with friends to see how they handle their email in-box…you might be a manager.If you consider bragging about a spreadsheet you developed…you might be a manager.If you have a folder filled with articles on how to improve meetings…you might be a manager. If you ever created a checklist to improve your checklists…you might be a manager.If you ever made a New Year’s resolution to read more business books…you might be a manager.If you’ve ever done research on how to improve your checklists…you might be a manager.If a slow spell at work makes you nervous…you might be a manager.If you rate airports by the number of free outlets they make available…you might be a manager.If you find it hard not to rate people solely by how well they do their job…you might be a manager. If a blog post by John Spence or Dan Rockwell nearly brings you to tears…you might be a manager.If you watched a TED video and thought to yourself…man, this could change my life…you might be a manager.And if the length of this blog post is starting to bother you because of all that’s on your plate…you might be a manager.Feel free to add to the list, folks. Have a great weekend!
Share on: WhatsApp Neymar also posted on Weibo a picture of himself with fellow Brazilian forward Hulk, who plays in the Chinese Super League for Shanghai SIPG.Even following the training-ground bust-up in the United States, after which Neymar appeared to storm off, his Barcelona team-mates said they wanted him to stay at the Camp Nou.“Neymar and I, we are very close and I want him to stay and I know the situation,” defender Gerard Pique told ESPN FC.“Right now he doesn’t know what to do and we are trying to help him — the ones (on the team) that are more close to him — to take the right decision.”PSG’s pursuit of Neymar has angered some in Spain, where football league chief Javier Tebas says he will file a complaint with UEFA for financial fair play breaches by the French club. Shanghai, China | AFP | Neymar hit the red carpet in Shanghai on Monday as speculation mounted that the Brazil star could be set to quit Barcelona for Paris Saint-Germain for a world-record 222 million euros.The 25-year-old striker is at the centre of an apparent tug of war between the two European giants in what would be the most expensive transfer fee in football history.A training spat with new Barcelona signing Nelson Semedo during a pre-season tour in Miami ramped up chatter that Neymar could be about to swap Spain for the French capital.Neymar, who has remained tight-lipped about the transfer rumours, posted a message for Chinese fans on Weibo, China’s equivalent of Twitter, after arriving for a promotional visit.“Ni Hao China! I’m Neymar Jr. and I’ve just arrived in China,” he wrote.“I’m in Shanghai at the moment. I would like to send a huge hug to all my Chinese fans, thank you very much for your support.”He later posed for a scrum of photographers and television journalists and answered questions about fashion, before attending an evening event for a clothing brand.
