Topological Phenomena in Artificial Materials
This talk will cover the design and realization of novel topological states and effects in acoustic artificial materials, focusing on higher-order topological states, non-Hermitian physics, and acoustic spin- and orbital angular momentum-related topological phenomena.
Overview
Over the past two decades, topological phases, originally emerging in condensed matter systems, have flourished in classical wave systems (e.g., photonic and acoustic platforms), unveiling rich topological physics and phenomena. In topological materials, the transport of light and sound exhibits topologically protected properties such as backscattering suppression and pseudo-spin locking, promising transformative applications in wave-based information and energy technologies.
