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…

Nonlinearity-induced corner states in a kagome lattice
K Prabith, Georgios Theocharis, Rajesh Chaunsali
Nonlinearity provides a powerful mechanism for controlling energy localization in structured dynamical systems. In this study, we investigate the emergence of nonlinearity-induced…

Edge States with Hidden Topology in Spinner Lattices
Udbhav Vishwakarma, Murthaza Irfan, Georgios Theocharis +1
Symmetries -- whether explicit, latent, or hidden -- are fundamental to understanding topological materials. This work introduces a prototypical spring-mass model that extends beyo…
