The long-range transport of deconfined magnetic hedgehogs

Spintronics is an emerging area of research that aims to develop devices that transmit, process and store information leveraging the intrinsic angular momentum of electrons, known as spin. A key objective of spintronics studies ...

The realization of a single-quantum-dot heat valve

While many research teams worldwide are trying to develop highly performing quantum computers, some are working on tools to control the flow of heat inside of them. Just like conventional computers, in fact, quantum computers ...

Metasurface enabled quantum edge detection

Metasurfaces provide unique platforms to realize exotic phenomena including negative refraction, achromatic focusing, and electromagnetic cloaking due to the engineered dielectric or metallic architectures. The intersection ...

Search for axions from nearby star Betelgeuse comes up empty

The elusive axion particle is many times lighter than an electron, with properties that barely make an impression on ordinary matter. As such, the ghost-like particle is a leading contender as a component of dark matter—a ...
