(Phys.org) —By introducing individual silicon atom 'defects' using a scanning tunnelling microscope, scientists at the London Centre for Nanotechnology have coupled single atoms to form quantum states. http://phys.org/news284207230.html Physics Wed, 03 Apr 2013 11:27:32 EST news284207230 Researchers at the National Institute of Standards and Technology have developed a new microscope able to view and measure an important but elusive property of the nanoscale magnets used in an advanced, experimental form of digital memory. The new instrument already has demonstrated its utility with initial results that suggest how to limit power consumption in future computer memories. http://phys.org/news282567626.html Physics Fri, 15 Mar 2013 12:00:38 EST news282567626 An assistant professor of physics at Indiana University-Purdue University Indianapolis (IUPUI) will be among a team of international researchers looking to advance the theory of quantum mechanics, a notion challenged by Albert Einstein and pursued by many of the top scientific minds during the past century. http://phys.org/news278936824.html Physics Fri, 01 Feb 2013 10:27:12 EST news278936824 Among the most important techniques developed in atomic physics over the past few years are methods that enable the storage and cooling of atoms and ions at temperatures just above absolute zero. Scientists from Bangalore and Mainz have now demonstrated in an experiment that captured ions can also be cooled through contact with cold atoms and may thus be stored in so-called ion traps in a stable condition for longer periods of time. This finding runs counter to predictions that ions would actually be heated through collisions with atoms. The results obtained by the joint Indo-German research project open up the possibility of conducting future chemical experiments to generate molecular ions at temperatures as low as those that prevail in interstellar space. http://phys.org/news273156285.html Physics Mon, 26 Nov 2012 13:00:01 EST news273156285 In an international scientific breakthrough, a Griffith University research team has been able to photograph the shadow of a single atom for the first time. http://phys.org/news260541204.html Physics Tue, 03 Jul 2012 13:33:34 EST news260541204 Scientists at the Cavendish Laboratory in Cambridge have used light to help push electrons through a classically impenetrable barrier. While quantum tunnelling is at the heart of the peculiar wave nature of particles, this is the first time that it has been controlled by light. Their research is published today, 05 April, in the journal Science. http://phys.org/news252844791.html Physics Thu, 05 Apr 2012 14:00:11 EST news252844791 Scientists realize one of the most elementary and oldest "gedanken" experiments in modern physics, namely, excitation of a single molecule with a single photon. This paves the way for further investigations in which single photons act as carriers of quantum information to be processed by single emitters. http://phys.org/news249651712.html Physics Tue, 28 Feb 2012 11:42:01 EST news249651712 Minced meat, bread, fruit juice and many other foods are packaged in a protective gas which extends their shelf life. There is currently no good method to check whether the packaging has the correct gas content. However, researchers in Atomic Physics and Packaging Logistics have developed a new laser instrument which could solve the problem. The first product is expected to be ready for market launch later in the autumn. http://phys.org/news238325353.html Chemistry Thu, 20 Oct 2011 10:29:23 EST news238325353 (PhysOrg.com) -- A Rydberg atom is one with an electron that spends most of its time far from the nucleus. Rydberg atoms, which are normally artificially produced, can have dimensions thousands of times larger than typical atoms or simple molecules. http://phys.org/news196360166.html Physics Mon, 21 Jun 2010 17:30:20 EST news196360166 By the logic of science, things simply shouldn't exist. The best scientific minds of several generations have reasoned that shortly after the Big Bang created the universe, matter and antimatter should have wiped each other out. http://phys.org/news194726882.html Physics Wed, 02 Jun 2010 19:49:05 EST news194726882 Scientists at the University of California, Berkeley, and Lawrence Berkeley National Laboratory in the US, have performed sophisticated laser measurements to detect the subtle effects of one of nature's most elusive forces - the "weak interaction". Their work, which reveals the largest effect of the weak interaction ever observed in an atom, is reported in Physical Review Letters and highlighted in the August 10th issue of APS's on-line journal Physics. http://phys.org/news169124688.html Physics Mon, 10 Aug 2009 12:20:01 EST news169124688
