Caldeira-Leggett master equation and medium temperatures
نویسنده
چکیده
The Markovian approximation of quantum dissipation has been reconsidered in the model of Caldeira and Leggett [Physica A 121 (1983) 587]. Their high temperature master equation has been generalized to medium temperatures, Two additional damping terms in the master equation have been derived and shown to assure the Lindblad form of the equation. A transient term in the density matrix has been found and expressed in a simple form.

Global solutions of the mean–field, very high temperature Caldeira–Leggett master equation
In this paper, global well–posedness as well as regularity of very high temperature Caldeira–Leggett models with repulsive Poisson coupling are proved by using Green function techniques and Fokker–Planck smoothing arguments along with kinetic energy and elliptic estimates.

متن کاملThe Emergence of Classicality via Decoherence: Beyond the Caldeira-Legget Environment
Maximally predictive states, as defined in recent work by Zurek, Habib and Paz, are studied for more elaborate environment models than a linear coupling to an oscillator bath (which has become known as the Caldeira-Leggett model). An environment model which includes spatial correlations in the noise is considered in the non-dissipative regime. The Caldeira-Leggett model is also re-considered in...
متن کاملQuantumRatchets at High Temperatures
Using the continued-fraction method we solve the Caldeira-Leggett master equation in the phase-space (Wigner) representation to study Quantum ratchets. Broken spatial symmetry, irreversibility and periodic forcing allows for a net current in these systems. We calculate this current as a function of the force under adiabatic conditions. Starting from the classical limit we make the system quanta...
متن کامل2 00 8 Approach to Thermal Equilibrium in the Caldeira - Leggett Model Fethi
We provide an explicit analytical calculation that shows the asymptotic approach of the one dimensional Caldeira-Leggett model to thermal equilibrium in the high temperature and weak coupling limit. We investigate a free particle and a harmonic oscillator system, using both the Lindblad and the nonLindblad type master equations for each case, and show that thermal equilibrium is reached exactly...
متن کاملRelaxation dynamics of a quantum Brownian particle in an ideal gas
We show how the quantum analog of the Fokker-Planck equation for describing Brownian motion can be obtained as the diffusive limit of the quantum linear Boltzmann equation. The latter describes the quantum dynamics of a tracer particle in a dilute, ideal gas by means of a translation-covariant master equation. We discuss the type of approximations required to obtain the generalized form of the ...
