Harmonic phonon bath

An important aspect of electron transfer is the accompanying reorganization of the solvent. The latter can be modeled as a phonon bath, or a collection of harmonic oscillators. Other models in terms of the... [Pg.578]

In order to investigate the dynamics of the charge carrier with the fluctuations caused by the harmonic oscillator bath, one can translate the total Hamiltonian eqn (12.72) into the interaction representation of the phonon Hamiltonian Hp. ... [Pg.324]

The role of two-phonon processes in the relaxation of tunneling systems has been analyzed by Silbey and Trommsdorf [1990]. Unlike the model of TLS coupled linearly to a harmonic bath (2.39), bilinear coupling to phonons of the form Cijqiqja was considered. In the deformation potential approximation the coupling constant Cij is proportional to (y.cUj. There are two leading two-phonon processes with different dependence of the relaxation rate on temperature and energy gap, A = (A Two-phonon emission prevails at low temperatures, and it is... [Pg.104]
