AB Throughout this project, the case of a composite system formed by a harmonic oscillator and a two-state atom will be studied; considering both affect each other asa consequence of a Jaynes-Cummings interaction, and being both coupled to different reservoirs that are assumed to be independent from each other. The effectsof the decoherence in the evolution of the populations and coherences will be analyzed; specifically the energy dissipation and the coherence loss, as well as the stationary states and the relevance of the Jaynes-Cummings interaction. Finally, thesolution of stochastic equations will be analyzed, particularly the evolution of theexpectation value of the position operator for the harmonic oscilator; for the case ofsimultaneous measurements in both subsystems, as well as for a measurement inthe harmonic oscillator when the two-state atom undergoes a decoherence process.
