WebDissipation is a decohering process by which the populations of quantum states are changed due to entanglement with a bath. An example of this would be a quantum system that can exchange its energy with a bath through the interaction Hamiltonian.If the system is not in its ground state and the bath is at a temperature lower than that of the system's, … WebA first analysis of the inelastic incoherent scattering (Buchenau et al. 1996) again shows this dynamical heterogeneity to be connected with the modes in the boson-peak region. The findings are consistent with the idea of localized modes, coexisting with the sound waves.
