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…
Dirac Solitons and Topological Edge States in the -Fermi-Pasta-Ulam-Tsingou dimer lattice
Rajesh Chaunsali, Panayotis G. Kevrekidis, Dimitri Frantzeskakis +1
We consider a dimer lattice of the Fermi-Pasta-Ulam-Tsingou (FPUT) type, where alternating linear couplings have a controllably small difference, and the cubic nonlinearity (-FP…
Stability of topological edge states under strong nonlinear effects
Rajesh Chaunsali, Haitao Xu, Jinkyu Yang +2
We examine the role of strong nonlinearity on the topologically-robust edge state in a one-dimensional system. We consider a chain inspired from the Su-Schrieffer-Heeger model, but…
Extreme control of impulse transmission by cylinder-based nonlinear phononic crystals
Rajesh Chaunsali, Matthew Toles, Jinkyu Yang +1
We present a novel device that can offer two extremes of elastic wave propagation --- nearly complete transmission and strong attenuation under impulse excitation. The mechanism of…
Demonstrating an in-situ topological band transition in cylindrical granular chains
Rajesh Chaunsali, Aman Thakkar, Eunho Kim +2
We numerically investigate and experimentally demonstrate an in-situ topological band transition in a highly tunable mechanical system made of cylindrical granular particles. This…
Linear and nonlinear dynamics of isospectral granular chains
R. Chaunsali, H. Xu, J. Yang +1
We study the dynamics of isospectral granular chains that are highly tunable due to the nonlinear Hertz contact law interaction between the granular particles. The system dynamics…
