Supersonic and multiple topological excitations in the driven Frenkel-Kontorova model with exponential interaction
arXiv:cond-mat/0010126 · doi:10.1103/PhysRevE.62.7315
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.
