A scientific seminar will be hosted by CERN on July 4, 2012 to discuss the latest results on the Higgs boson. The CMS and ATLAS experiments will present the initial results of the 2012 data analysis at this event, which comes as a curtain raiser for ICHEP, a key particle physics conference to be conducted in Melbourne, Australia.

Scientists from the Max Planck Institute of Quantum Optics, Harvard University, and Caltech have succeeded in increasing the lifetime of a quantum bit (qubit) in a diamond crystal to over a second at room temperature. In earlier attempts, the storage time of this kind of qubit was only a few thousandths of a second.
The Hall effect has been observed for the very first time in a gas of ultracold atoms by researchers from the National Institute of Standards and Technology (NIST). This discovery will enable scientists to enhance their knowledge about the physics of the quantum Hall effect and superfluidity.

Daniel Grumiller and Gabriela Mocanu, researchers at the Vienna University of Technology, have devised a new technique to demonstrate the existence of theoretical ‘axions,’ which may encircle a black hole and extort energy from it. This may result in the emission of gravity waves, which can then be calculated.

University of Bonn researchers have shown how one atom can be split into two halves, taken apart and then joined together again. The researchers strived to build quantum mechanics bridges by making the atom come into contact with adjacent atoms while it is being taken apart so that it functions like a bridge spanning between two pillars. The results are published in the "Proceedings of the National Academy of Sciences” journal.

Within the exotic world of macroscopic quantum effects, where fluids flow uphill, wires conduct without electrical resistance and magnets levitate, there is an even stranger family of "unconventional" phenomena...
In quantum physics physical processes in condensed matter and other many-body systems can often be described with quasiparticles. In Innsbruck, for the first time Rudolf Grimm’s team of physicists has succeeded in experimentally realizing a new quasiparticle - a repulsive polaron - in an ultracold quantum gas. The scientists have published their results in the online issue of the journal Nature.
Hundreds of string theorists meet each year to discuss their research at an international conference. STRINGS 2012 takes place in Munich, and is organized jointly by LMU Munich, the Max-Planck Institute for Physics, the ...
