Splitting of Waves in Rotor-in-Rotor Nonlocal Metamaterials by Internal Rotor Coupling
SSRN Electronic Journal, 2022 Mechanical metamaterials can be used to control wave propagation because they are flexibly adjustable. In this paper, a one-dimensional rotor-in-rotor metamaterial with internal rotor coupling is proposed. This metamaterial introduces a new connection between lattices into a rotor-in-rotor system to produce a nonlocal metamaterial.

Non-equilibrium steady states for chains of four rotors
, 2016 We study a chain of four interacting rotors (rotators) connected at both ends to stochastic heat baths at different temperatures. We show that for non-degenerate interaction potentials the system relaxes, at a stretched exponential rate, to a non ...
