- W2025117619 abstract "The problem of vibrational energy transfer in ordered quasi-one-dimensional molecular structures is considered. The model of nonlinear lattice of classical nonlinear oscillators is investigated numerically in a broad range of parameter variations (anharmonisity of vibron and phonon subsystems, and nonlinear coupling between them). The conditions for the formation of soliton-like excitation of different types from initial local disturbances are determined. A numerical simulation showed that new types of supersonic anharmonic two-component solitons in an anharmonical lattice of harmonic oscillators can be excited. This type of nonlinear soliton-like excitation can be important in understanding the electron and energy transport mechanisms in molecular crystals, molecular aggregates, molecular oriented films and biopolimers." @default.
