Z. Ivic et al., EFFECTS OF QUANTUM-LATTICE FLUCTUATIONS ON MULTIQUANTA DAVYDOV-LIKE SOLITONS IN A MOLECULAR CHAIN, Journal of physics. Condensed matter, 9(2), 1997, pp. 413-426
The dressing effect due to the quantum nature of phonons may cause the
creation of bound states of several vibrons in the molecular chain. T
he possibility of creating soliton states of this type is discussed fo
r the simple Frohlich one-dimensional model. The regions of the system
parameter space where different mechanisms dominate the behaviour of
such entities are characterized.
