Phys. Rev. Lett. 84, 1374–1377 (2000)Completely Positive Quantum DissipationReceived 9 April 1999; published in the issue dated 14 February 2000 A completely positive master equation describing quantum dissipation for a Brownian particle is derived starting from microphysical collisions, exploiting a recently introduced approach to subdynamics of a macrosystem. The obtained equation can be cast into Lindblad form with a single generator for each Cartesian direction. Temperature dependent friction and diffusion coefficients for both position and momentum are expressed in terms of the collision cross section. © 2000 The American Physical Society URL:
