SOLITONS IN NON-DEGENERATED BISTABLE SYSTEMS

Soliton-like elementary excitations in bistable systems, whose energies of different equilibrium states are not equal, are considered. Particular physical systems described by a common Hamiltonian are discussed in the framework of proposed approach. The analysis of the continuum equation of motion demonstrates the existence in such systems both of the nontopological solitons connected with energy transfer and topological solitons describing the transitions between different states (state transfer). Computer simulation data are compared with solutions of analytical models.
