The ability to hide an arbitrary object with a cloak at a distance from the object is a unique task in photonics research, although the phenomenon is yet to be realized in practice. In a recent study now published in Light: ...
(Phys.org)—Physicists have proposed a way to braid three beams of light by guiding the beams along swirling, vortex-shaped defects in the optical medium through which the beams travel. The braided light would have an unusual ...
(PhysOrg.com) -- As researchers strive to increase the density and functionality of circuit elements onto computer chips, one newer option they have is a memory resistor (or “memristor”), the fourth passive circuit element. ...
(Phys.org)—PFC supported scientists at JQI have created the first controllable atomic circuit that functions analogously to a superconducting quantum interference device (SQUID) and allows operators to select a particular ...
