Phonons are the quantum units of mechanical vibration. They describe how motion propagates through a solid at the smallest ...

The nonlinear susceptibility is a measure of a material's nonlinear response to an applied electric field. It determines the strength of the nonlinear effects and is related to the crystal's symmetry ...

Using two optically trapped glass nanoparticles, researchers observed a novel collective Non-Hermitian and nonlinear dynamic driven by nonreciprocal interactions. This contribution expands traditional ...

A single MXene-based optical gate switches between seven Boolean logic functions via voltage, enabling trainable photonic ...
