New experiments challenge fundamental understanding of electromagnetism
(Phys.org)—A cornerstone of physics may require a rethink if findings at the National Institute of Standards and Technology (NIST) are confirmed. Recent experiments suggest that the most rigorous predictions ...
China to scrap purchase tax on electric vehicles
China will exempt electric cars and other types of "new energy" vehicles from purchase tax, the government said, as it seeks to reduce pollution and conserve resources.
16 atomic ions simulate a quantum antiferromagnet
(Phys.org) —Frustration crops up throughout nature when conflicting constraints on a physical system compete with one another. The way nature resolves these conflicts often leads to exotic phases of matter ...
Silicon oxide memories transcend a hurdle
A Rice University laboratory pioneering memory devices that use cheap, plentiful silicon oxide to store data has pushed them a step further with chips that show the technology's practicality.
Could Maxwell's Demon Exist in Nanoscale Systems?
Building quantum states with individual silicon atoms
(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.
Tunable quantum cascade laser
New technique for cooling molecules may be stepping stone to quantum computing
(Phys.org) —The next generation of computers promises far greater power and faster processing speeds than today's silicon-based based machines. These "quantum computers"—so called because they would harness ...
Laser light used to cool object to quantum ground state
For the first time, researchers at the California Institute of Technology (Caltech), in collaboration with a team from the University of Vienna, have managed to cool a miniature mechanical object to its lowest ...
Infrared light fills a "gap" in iron-based superconductor research
(Phys.org) —Superconductors are a fascinating group of materials in which electrons can flow with almost zero resistance. They have the potential to revolutionize electronics and power distribution, but ...
