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…
Wave propagation in an elastic lattice with non-reciprocal stiffness and engineered damping
Harshit Kumar Sandhu, Saurav Dutta, Rajesh Chaunsali
Nonreciprocal wave propagation allows for directional energy transport. In this work, we systematically investigate wave dynamics in an elastic lattice that combines nonreciprocal…
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…
Remote Nucleation and Stationary Domain Walls via Transition Waves in Tristable Magnetoelastic Lattices
Anusree Ray, Samanvay Anand, Vivekanand Dabade +1
We present a magnetoelastic lattice in which a localized external magnetic field, generated by an assembly of fixed magnets, tunes the potential landscape to create monostable, bis…
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…
