Temporal evolution of a driven optomechanical system in the strong coupling regime

L Medina-Dozal,
J Récamier,
H M Moya-Cessa
et al.

Abstract: We obtain a time-evolution operator for a forced optomechanical quantum system using Lie algebraic methods when the normalized coupling between the electromagnetic field and a mechanical oscillator, G/ω m , is not negligible compared to one, i.e., the system operates in the strong-coupling regime. Due to the forcing term, the interaction picture Hamiltonian contains the number operator in the exponents, and in order to deal with it, we approximate these… Show more

“…We have studied the atom-field interaction in the strong coupling regime [28] at finite temperature when the field is initially in a coherent state and in the dispersive regime. By using superoperator techniques, we manage to solve the master equation for this system and have calculated the linear entropy.…”
