Abstract
The properties of the intramolecular vibrational excitation (vibron) in a quasi 1D macromolecular structure are studied. It is supposed that due to the vibron interaction with optical phonon modes, a vibron might form partially dressed small polaron states. The properties of these states are investigated in dependence on the basic system parameters and temperature of a thermal bath. We also investigate the process of damping of the polaron amplitude as a function of temperature and vibron-phonon coupling strength. Two different regimes of the polaron damping are found and discussed.
Highlights
The knowledge of exciton properties and especially physics of exciton transport in quasi 1D structures is very important in many fields of material sciences
It is pertinent to mention the problem of charge and energy transport in biological macromolecules (MCs) and the problem of the quantum information transport in quantum circuits, especially in realistic conditions, where a thermal bath is an important source of quantum information losses
One of the most important processes is the photosynthesis, in which a photon quantum is absorbed by special cell structures as an electronic excitation
