Physicists Measure Elusive 'Persistent Current' That Flows Forever
(PhysOrg.com) -- Physicists at Yale University have made the first definitive measurements of "persistent current," a small but perpetual electric current that flows naturally through tiny rings of metal wire ...
Solar Cell Researcher Explores Nanotech Ideas
(PhysOrg.com) -- A UT Dallas researcher envisions a time soon when plastic sheets of solar cells are inexpensively stamped out in factories and then affixed to cell phones, laptops and other power-hungry mobile ...
In brief: A tiny, tunable well of light, and a string theorist's toolbox
Promising photonic devices, and theorists attempt to determine whether particle physics and string theory can be reconciled.
Researchers find quantum errors do compute
(PhysOrg.com) -- Physicists from The University of Queensland have found the emerging field of quantum computing may be more stable than previously thought.
Quantum ghosts are helpful
(PhysOrg.com) -- The idea that far distant particles can somehow 'talk' to each other worried Einstein so much that he called it 'spooky action at a distance'.
Quantum dots and nanomaterials: Ingredients for better lighting and more reliable power
Imagine flexible lighting devices manufactured by using printing techniques. Imagine solar power sources equally as reliable and as portable as any conventional power source.
Researchers discover a potential on-off switch for nanoelectronics
As electronic circuits shrink from finely etched lines in silicon wafers to nearly elusive proportions, researchers at the U.S. Department of Energy's Lawrence Berkeley National Laboratory and Columbia University ...
Quantum technologies move a step closer with the demonstration of an 'entanglement' filter
(PhysOrg.com) -- A team of physicists and engineers has demonstrated an optical device that filters two particles of light (or photons) based on the correlations between their polarisation that are only allowed in the seemingly ...
