摘要: Abstract The quantum dynamics of a strongly coupled dissipative system toward thermal equilibrium is investigated by means the Jaynes-Cummings model with relaxation mechanisms. Our ensures that evolves in time to correct canonical distribution equilibrium. quantal master equation expended terms eigenstates whole system. evolution elements reduced density matrix described vector tri-diagonal differential equation. process reveals itself through these resulting distribution. Quantum characteristics are found both short regime and long regime. characterized decoherence process, which represents phase relaxation, whereas dominated diagonal energy relaxation.
