Vacuum in optical cavity can change material's magnetic state without laser excitation

Researchers in Germany and the U.S. have produced the first theoretical demonstration that the magnetic state of an atomically thin material, α-RuCl3, can be controlled solely by placing it into an optical cavity. Crucially, ...

New technique uses near-miss particle physics to measure wobbling tau particles

One way physicists seek clues to unravel the mysteries of the universe is by smashing matter together and inspecting the debris. But these types of destructive experiments, while incredibly informative, have limits.

Researchers measure magnetic field in eclipse medium of a spider pulsar PSR J2051-0827

Spider pulsars are a subclass of millisecond pulsar binary systems with low mass companions in short-period orbits. In spider pulsars, the pulsar wind and electromagnetic emission ablate and may destroy the companion.

Pulsars may make dark matter glow

The central question in the ongoing hunt for dark matter is: what is it made of? One possible answer is that dark matter consists of particles known as axions. A team of astrophysicists, led by researchers from the universities ...
