    "abstract": "We show a completely analytical approach to the decoherence induced by a zero\ntemperature environment on a Brownian test particle. We consider an Omhic\nenvironment bilinearly coupled to an oscillator and compute the master\nequation. From diffusive coefficients, we evaluate the decoherence time for the\nusual quantum Brownian motion and also for an upside-down oscillator, as a toy\nmodel of a quantum phase transition.",
