Single-particle limit of a topological edge state in a locally resonant band gap
Garigipati Sai Srikanth, Kai Qian, Ian Frankel +3
Topological metamaterials promise unprecedented wave control. Here, we theoretically and numerically investigate a one-dimensional Su-Schrieffer-Heeger (SSH)-inspired stiffness dim…

Observation of mechanical kink control and generation via phonons
Kai Qian, Nan Cheng, Francesco Serafin +4
Kinks (or domain walls) are localized transitions between distinct ground states associated with a topological invariant, and are central to many phenomena across physics, from con…
