Resumen de Linear entropy in the atom-field interaction at finite temperature (7 pages)

R. Juárez Amaro, Héctor Manuel Moya Cessa

• We study the atom-field interaction at finite temperature and in the dispersive regime. We show that the master equation for this sytem may be solved with the use of superoperator techniques. We calculate the linear entropy in case the field is initially in a coherent state and the atom in a superposition of its ground and excited states.
