College Pk: American Physical Soc, v. 44, n. 12, p. 7923-7928, 1991.1050-2947http://hdl.handle.net/11449/31015The quantum Brownian particle, immersed in a heat bath, is described by a statistical operator whose evolution is ruled by a generalized master equation (GME). The heat bath's degrees of freedom are considered to be either white-noise or colored-noise correlated, while the GME is considered under either the Markov or non-Markov approaches. The comparisons between these considerations are fully developed, and their physical meaning is discussed.7923-7928engArtigo10.1103/PhysRevA.44.7923WOS:A1991GW60400014Acesso abertoWOSA1991GW60400014.pdf
