Scientists working at the Institut Laue-Langevin, one of the world's leading centres for neutron science, have carried out the first investigation of two-dimensional fermion liquids using neutron scattering, and discovered a new type of very short wave-length density wave. The team believe their discovery, published in Nature, will interest researchers looking at electronic systems, since high temperature superconductivity could result from this type of density fluctuations. http://phys.org/news252149896.html Physics Wed, 28 Mar 2012 13:00:01 EST news252149896 (PhysOrg.com) -- A Cambridge team have built a semiconductor chip that converts electrons into a quantum state that emits light but is large enough to see by eye. Because their quantum superfluid is simply set up by shining laser beams on the device, it can lead to practical ultrasensitive detectors.  Their research is published today, 08 January in Nature Physics. http://phys.org/news245317266.html Physics Mon, 09 Jan 2012 07:41:16 EST news245317266 Nature knows two opposite types of solids: one that emerges upon compression from a liquid and a second that appears if the pressure on a liquid is reduced. While the former is typical for substances in our everyday life the latter occurs for example in a dense quantum liquid of electrons (such as in metals) or ions (in exotic white dwarf or neutron stars). Now it has been shown that there exists yet a third form of matter that inherits both of these properties. This unusual behaviour has been predicted to exist in crystals of excitons – hydrogen atom-like bound states of electrons and holes – in a semiconductor quantum well placed in a strong electric field. http://phys.org/news232193476.html Physics Wed, 10 Aug 2011 11:11:45 EST news232193476
