DOI: 10.1103/physrevb.104.054103
Abstract: As a potential degree of freedom, the chirality of phonons is expected to become a carrier of information. Exploring the phonon mode that can stably maintain chirality along a certain transport path is the basis… read more here.

DOI: 10.1364/ol.482614
Abstract: Dirac points (DPs) and Weyl points (WPs) have received much attention in photonic crystals (PhCs) and three-dimensional (3D) metamaterials research due to the robust surface states and Fermi arcs. In this work, two pairs of… read more here.
