Quantum physicists pave the way for investigating new states of matter in ultracold atom mixtures Scientists of the Institute for Quantum Optics and Quantum Information (IQOQI) in Innsbruck, Austria, have reached a milestone in the exploration of quantum gas mixtures. In an international first, the research group led by Rudolf Grimm and Florian Schreck has succeeded in producing controlled strong interactions between two fermionic elements - lithium-6 and potassium-40. This model system not...

Direct measurements allow detailed look at how quarks of different flavors contribute to spin Scientists hoping to unravel the mystery of proton spin at the Relativistic Heavy Ion Collider (RHIC), a 2.4-mile-circumference particle accelerator at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory, have a new tool at their disposal "” the first to directly explore how quarks of different types, or "flavors," contribute to the overall spin of the proton. The technique,...

After less than three weeks of heavy-ion running, the three experiments studying lead ion collisions at the LHC have already brought new insight into matter as it would have existed in the very first instants of the Universe's life. The ALICE experiment, which is optimised for the study of heavy ions, published two papers just a few days after the start of lead-ion running. Now, the first direct observation of a phenomenon known as jet quenching has been made by both the ATLAS and CMS...

The Large Hadron Collider (LHC) has taken new steps by smashing together lead ions instead of protons to create a "mini-Big Bang." Scientists working at the particle smasher achieved the feat on November 7. Experts working with the LHC created temperatures a million times hotter than the center of the sun. The LHC lies under the French-Swiss border near Geneva in a 16-mile long circular tunnel. The world's highest-energy particle accelerator has been colliding protons in search for the...

Researchers working at the world's highest-energy particle accelerator on the Franco-Swiss border are nearly set to create the Big Bang on a miniature scale. Since 2009, the Large Hadron Collider (LHC) has been smashing protons together, trying to shed light on the essential nature of matter. But for the upcoming experiments, planned for early November and running for four weeks, the team will have the accelerator collide lead ions instead. The collider, managed by the European...

The Alpha Magnetic Spectrometer-2 (AMS) destined for the International Space Station already is collecting cosmic ray signatures, even as it sits in a work stand at the Space Station Processing Facility at NASA's Kennedy Space Center in Florida, said Prof. Samuel Ting, the principal investigator for the program. It "Ëœs not making any grand discoveries yet, since the particles it is picking up were stripped of some of their qualities when they passed through Earth's atmosphere. But...
