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 ...

Researchers have developed a nonlinear galloping-driven triboelectric-electromagnetic hybrid generator for harvesting ...

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 photon enters a tiny disk of layered crystal no wider than a human hair. It circles the rim, bouncing along atomically ...
