Abstract
The temperature-dependent behaviour of localized excitons in a linear molecular α-helix chain model is investigated. After transforming Davydov’s original Hamiltonian for the α-helix soliton to include Bogoliubov’s variational theorem, the temperature dependence of the “threshold” of solitonic solution is obtained. We also investigated the damping of a soliton under the influence of the thermal bath. The approach is based on the consequent microscopic treatment in context of quantum Langevin equation.
