Periodic wave solutions in nonlinear equations play a pivotal role in understanding phenomena across fluid dynamics, optical physics, and quantum mechanics. Their stability—whether a wave maintains ...

This course is designed to provide a theoretical background on the propagation of elastic stress waves in solids with periodic variation in geometry or elastic properties, a review of experimental ...

Two independent teams of physicists have used ultracold atomic gases to demonstrate how a little bit of disorder can paralyse a quantum system — an effect called “Anderson localization”. Their ...

A quiet revolution is taking shape in the world of physics, and it doesn’t rely on exotic particles or massive particle colliders. Instead, it begins with something much more familiar—sound.

An international team of researchers has succeeded in steering light waves deep into “forbidden” regions of photonic crystals by manipulating the shape of the waves. The technique, which was developed ...

Strange pulses that don't seem to abide by the laws of particle physics have been detected in Antarctica. These radio waves, emanating from below the ice, could be evidence of dark matter and have ...

The discovery could explain how the corona's temperature greatly exceeds that of the Sun's surface, and identify a key driver ...
