Résumé : A master equation was derived from von Neumann equation to study the dynamics of a quantum system interacting with its environment. The equation was obtained by perturbative expansion with respect to the coupling parameter between the system and its environment. The equation reduces to the non-Markovian Redfield equation, if the changes in the density of states of the environment induced by the system is neglected. Numerical simulations were carried out of the spin-GORM model that show the accuracy of master equation.
