The experimental demonstration of topological dissipation in photonic resonators
So far, physicists have primarily studied topological phases in conservatively coupled systems. These are systems with dynamics that do not dissipate and a phase space that does not shrink over time. They are in stark contrast with dissipative system.....»»

A strategy for the spin-acoustic control of silicon vacancies in a 4H silicon carbide-based bulk acoustic resonator
Bulk acoustic resonators—stacked material structures inside which acoustic waves resonate—can be used to amplify sounds or filter out undesired noise. These resonators have found wide use in today's RF telecommunication, like Front-End Modules (F.....»»
Quantum computers in 2023: How they work, what they do, and where they"re heading
In June, an IBM computing executive claimed quantum computers were entering the "utility" phase, in which high-tech experimental devices become useful. In September, Australia's Chief Scientist Cathy Foley went so far as to declare "the dawn of the q.....»»
Vectorial spin-orbital Hall effect of light upon tight focusing and experimental observation in azopolymer films
A soccer player can kick a static ball on its side, forcing the ball to rotate and travel in an arc trajectory, left or right curved, depending on the ball's rotation sense. This requires skill/experience. And if the ball is not static but approaches.....»»
New technique accomplishes precise control of photonic angular momentum
Rotating objects carry angular momentum; this fact extends even to the tiniest of particles, such as photons. Photons possess not one but two distinct forms of angular momentum: spin angular momentum (SAM) and orbital angular momentum (OAM)......»»
