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 technical paper titled “Programmable Nonlinear Quantum Photonic Circuits” was published by researchers at Niels Bohr Institute, University of Copenhagen, University of Bristol, and Ruhr-Universitat ...
