Phonons are the collective vibrations that move through a solid. They can be thought of as waves traveling across the atomic ...

A pair of photons enters an optical maze, and sometimes they leave as something new. Not new in the everyday sense, since both were still photons when they came out.

When a magnetic material is bombarded with short pulses of laser light, it loses its magnetism within femtoseconds (10 –15 seconds). The spin, or angular momentum, of the electrons in the material ...

In a new study ( Nature Physics, "Orbital Seebeck effect induced by chiral phonons" ), researchers developed the most ...

Photons can have half-integer values of angular momentum when they are confined to fewer than three dimensions. That is the conclusion of physicists in Ireland, who have revived an experiment first ...

During the 2026 Winter Olympics, athletes will leap off ramps, slide across ice and spin through the air. These performances will look different to my students who have studied physics through sports.

Optical vortices are currently one of the most intensively studied topics in optics. These light beams, which carry orbital angular momentum (OAM), have been successfully utilized in the visible and ...

A team of EPFL researchers has developed an AI algorithm that can model complex dynamical processes while taking into account the laws of physics—using Newton's third law. Their research is published ...
