Current Quantum Physics News Events, Discoveries and Articles
Small ... smaller ... smallest? ASU researchers create molecular diode
Recently, at Arizona State University's Biodesign Institute, N.J. Tao and collaborators have found a way to make a key electrical component on a phenomenally tiny scale. Their single-molecule diode is described in this week's online edition of Nature Chemistry. (2009-10-13)
UA scientists discover quantum fingerprints of chaos
Chaotic behavior is the rule, not the exception, in the world we experience through our senses, the world governed by the laws of classical physics. (2009-10-08)
Atoms don't dance the 'bose nova'
Hanns-Christoph Naegerl's research group has investigated how ultracold quantum gases behave in lower spatial dimensions. They successfully realized an exotic state, where, due to the laws of quantum mechanics, atoms align along a one-dimensional structure. (2009-09-04)
Precise Radio-Telescope Measurements Advance Frontier Gravitational Physics
Scientists using a continent-wide array of radio telescopes have made an extremely precise measurement of the curvature of space caused by the Sun's gravity, and their technique promises a major contribution to a frontier area of basic physics. (2009-09-02)
MU Researcher Investigates the Basis of Einstein's First Approximation in the Theory of Relativity
In his discussion of accelerated motion on page 60 of The Meaning of Relativity, Albert Einstein made an approximation that allowed him to develop the theory of relativity further. (2009-07-16)
Tossing a coin in the microcosm
When you toss a coin, you either get heads or tails. By contrast, things are not so definite at the microcosmic level. An atomic 'coin' can display a superposition of heads and tails when it has been thrown. (2009-07-10)
NIST physicists demonstrate quantum entanglement in mechanical system
Physicists at the National Institute of Standards and Technology (NIST) have demonstrated entanglement-a phenomenon peculiar to the atomic-scale quantum world-in a mechanical system similar to those in the macroscopic everyday world. (2009-06-04)
Evidence of macroscopic quantum tunneling detected in nanowires
A team of researchers at the University of Illinois has demonstrated that, counter to classical Newtonian mechanics, an entire collection of superconducting electrons in an ultrathin superconducting wire is able to "tunnel" as a pack from a state with a higher electrical current to one with a notably lower current, providing more evidence of the phenomenon of macroscopic quantum tunneling. (2009-05-28)
MIT reels in RNA surprise with microbial ocean catch
An ingenious new method of obtaining marine microbe samples while preserving the microbes' natural gene expression has yielded an unexpected boon: the presence of many varieties of small RNAs - snippets of RNA that act as switches to regulate gene expression in these single-celled creatures. (2009-05-14)
Caltech physicists detect entanglement of one photon shared among four locations
Scientists at the California Institute of Technology (Caltech) have developed an efficient method to detect entanglement shared among multiple parts of an optical system. (2009-05-11)
