  • Thanks to the acoustoelectric effect, we have demonstrated how non-Hermitian skin effect breaks the principle of bulk-edge correspondence in piezoelectric solids. It’s surprising to see the in-gap edge states appearing fully delocalized with proper losses.

About

Dr. Gao has keen interest in wave mechanics and engineering, in particular the interdisciplinary frontiers of phononic crystals, acoustic/mechanical metamaterials and topological insulators. By using numerical, experimental, and theoretical approaches, Dr. Gao and his collaborators intend to explore novel acoustical and mechanical phenomena in man-made metamaterials and structures, and further promote the possible applications for efficient noise control, vibration shielding, signal processing, integrated phononics and others.
