title: Supersonic and multiple topological excitations in the driven frenkel-kontorova model with exponential interaction
abstract: The criteria for the existence of supersonic and multiple topological excitations (kinks) in the driven Frenkel-Kontorova model (a chain of atoms placed into an external periodic potential) with anharmonic (exponential) interatomic interactions are studied.
