We consider a pair of linearly coupled harmonic oscillators to explore the decoherence phenomenon induces by interaction of a quantum system with a classical environment using Feynman path’s integral method. We determine the DCHO propagator afterwards thermodynamics parameters associated to the system. We show numerically that one can reduce decoherence of a system by coupling this one to a driven harmonic oscillator or by carrying this system to the resonance.
