Instability of Hysteretic Phase Interfaces in a Mean-Field Model with Inhomogeneities

Instability of Hysteretic Phase Interfaces in a Mean-Field Model with Inhomogeneities

.We study a system of nonidentical bistable particles that is driven by a dynamical constraint and coupled through a nonlocal mean-field. Assuming piecewise affine constitutive laws we prove the existence of traveling wave solutions and characterize their dynamical stability. Our findings explain the two dynamical regimes for phase interface that …
