    "abstract": "We consider the problem of decoherence and relaxation of open bosonic quantum\nsystems from a perspective alternative to the standard master equation or\nquantum trajectories approaches. Our method is based on the dynamics of\nexpectation values of observables evaluated in a coherent state representation.\nWe examine a model of a quantum nonlinear oscillator with a density-density\ninteraction with a collection of environmental oscillators at finite\ntemperature. We derive the exact solution for dynamics of observables and\ndemonstrate a consistent perturbation approach.",
