Abstract: Skin effect is one of the intriguing phenomena exhibited by non-Hermitian wave systems. It reflects the localization of the modes at the boundaries of the structure. We demonstrated the skin effect for elastic waves propagating… read more here.

DOI: 10.1073/pnas.2422355122
Abstract: Significance Photon–phonon coupling plays a critical role in light–matter interaction. Reductions of phonons in specific modes (cooling) can be realized through anti-Stokes light scattering, a nonlinear up-conversion process by absorbing phonons. This ability to coherently… read more here.
