    "abstract": "We study the behavior of a subsystem (harmonic oscillator) in contact with a\nthermal reservoir (finite set of uncoupled harmonic oscillators). We exactly\nsolve the eigenvalue problem and obtain the temporal evolution of the dynamical\nvariables of interest. We show how the subsystem goes to equilibrium and give\nquantitative estimates of the Poincar\\\u0027e recurrence times. We study the\nbehavior of the subsystem mean ocuppation number in the limit of a dense bath\nand compare it with the expected exponential decay law.",
