(Phys.org)—Researchers have designed a nanoscale device that, under ideal conditions, can confine a "bit" of light (that is, light with a single precise energy value) for an infinite amount of time. Although a physically ...
(Phys.org) —Within the mammalian inner ear, or cochlea, a remarkable but and long-debated phenomenon occurs: As they move from the base of the cochlea to its apex, traveling fluid waves – that is, surface waves, in which ...
(Phys.org) —Optical transistors and switches are fundamental in both classical and quantum optical information processing. A key objective in optics research is determining and developing the structural and performance ...
(PhysOrg.com) -- "Carbon nanotubes have a lot of really nice properties that make them good for photonics," Laurent Vivien tells PhysOrg.com. Ever since the discovery that carbon nanotubes have photoluminescence when encapsulated ...
(PhysOrg.com) -- “Quantum wells have been instrumental in telecommunications, enabling light amplification,” Patanjali Kambhampati tells PhysOrg.com, “but theory has suggested that a very small - colloidal - quantum ...
A group of political scientists from Harvard University, working with a colleague from Yale University, has found via simulations that politically motivated gerrymandering in the U.S. tends to cancel out as both sides change ...
To accurately diagnose and treat diseases, doctors and researchers need to see inside bodies. Medical imaging tools have come a long way since the humble X-ray, but most existing tools remain too coarse to quantify numbers ...
