Exact solution of the Hu-Paz-Zhang master equation
G. W. Ford,R. F. O'Connell +1 more
TL;DR: In this paper, the Hu-Paz-Zhang equation is applied to the motion of a Gaussian wave packet and to that of a pair of such wave packets, and an exact general solution is obtained in the form of an expression for the Wigner function at time t.
Journal ArticleDOI
Quantum measurement and decoherence
TL;DR: In this article, closed form expressions for wave packet spreading and the attenuation of coherence of a pair of wave packets are obtained, exact within the context of linear passive dissipation.
Journal ArticleDOI
Master Equation for an Oscillator Coupled to the Electromagnetic Field
TL;DR: In this paper, the macroscopic description of a quantum oscillator with linear passive dissipation is formulated in terms of a master equation for the reduced density matrix, which enables one to obtain an expression for the general term in the weak coupling expansion.
Journal ArticleDOI
Driven systems and the Lax formula
G. W. Ford,R. F. O'Connell +1 more
TL;DR: In this paper, the Lax formula for two-time correlations has been applied to two driven quantum systems: the oscillator and the two-level atom, and it has been shown explicitly that weak coupling approximation does not include quantum corrections to the Onsager regression hypothesis of classical statistical physics.
Journal ArticleDOI
