    "abstract": "A completely positive master equation describing quantum dissipation for a\nBrownian particle is derived starting from microphysical collisions, exploiting\na recently introduced approach to subdynamics of a macrosystem. The obtained\nequation can be cast into Lindblad form with a single generator for each\nCartesian direction. Temperature dependent friction and diffusion coefficients\nfor both position and momentum are expressed in terms of the collision\ncross-section.",
