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

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

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.

Schematic of a single photon with zero angular momentum (green) splitting into two photons (red) with either zero or opposite angular momenta (sketched through the spatially varying color), which adds ...

Explore the story of our solar system’s formation, tracing how a vast cloud of gas and dust collapsed under gravity, collisions, and angular momentum to create a thin, spinning protolanetary disc.
