Subsonic Phase Transition Waves in Bistable Lattice Models with Small Spinodal Region

Subsonic Phase Transition Waves in Bistable Lattice Models with Small Spinodal Region

Phase transitions waves in atomic chains with double-well potential play a fundamental role in materials science, but very little is known about their mathematical properties. In particular, the only available results about waves with large amplitudes concern chains with piecewise-quadratic pair potential. In this paper we consider perturbations of a …
