Weak equivalence principle violated in gravitational waves

The Weak equivalence principle (WEP) is a key aspect of classical physics. It states that when particles are in freefall, the trajectories they follow are entirely independent of their masses. However, it is not yet clear ...

Best evidence yet for existence of anyons

A small team of researchers at Purdue University has found the strongest evidence yet of the existence of abelian anyons. They have written a paper describing experiments they conducted designed to reveal the existence of ...

Composing new proteins with artificial intelligence

Proteins are the building blocks of life, and consequently, scientists have long studied how they can improve proteins and design completely new proteins that perform new functions and processes.

Setting up fundamental bases for information metasurfaces

When illuminated by electromagnetic waves, subwavelength-scale particles of metasurfaces can couple the incident energy to free space with controllable amplitude, phase and polarizations, such that the transmitted wave can ...

Improving the manipulation of microparticles by sound

A simple but accurate theory of how sound interacts with small particles has been developed by theoretical physicists at RIKEN. This advance will help to improve the manipulation of microparticles by sound.
