The double Caldeira–Leggett model: Derivation and solutions of the master equations, reservoir-induced interactions and decoherence
Cacheffo, A.; Moussa, M.H.Y.; de Ponte, M.A. - In: Physica A: Statistical Mechanics and its Applications 389 (2010) 11, pp. 2198-2217
reservoir. After deriving and solving the master equation for each case, we analyze the decoherence process of particular … entanglements in the positional space of both oscillators. To analyze the decoherence mechanism we have derived a general decay …-induced interaction, which gives rise to interesting collective damping effects, such as the emergence of relaxation- and decoherence …

General aspects of decoherence and dissipation of linearly coupled oscillators
José, W. Duarte; Nemes, M.C.; Toledo Piza, A.F.R. de - In: Physica A: Statistical Mechanics and its Applications 283 (2000) 3, pp. 359-368
We introduce an alternative nonperturbative method to the master equation formalism of describing the evolution of coupled linear systems. The method utilizes the spectral distribution of the normal modes of the complete system to calculate the evolution of the dynamical variables. The dynamical...
