Viscosity in the escape-rate formalism
S. Viscardy, P. Gaspard
We apply the escape-rate formalism to compute the shear viscosity in terms of the chaotic properties of the underlying microscopic dynamics. A first passage problem is set up for t…
Quantum master equation for a system influencing its environment (letter version)
Massimiliano Esposito, Pierre Gaspard
We derive a new perturbative quantum master equation for the reduced density matrix of a system interacting with an environment (with a dense spectrum of energy levels). The total…
Spin relaxation in a complex environment
Massimiliano Esposito, Pierre Gaspard
We report the study of a model of a two-level system interacting in a non-diagonal way with a complex environment described by Gaussian orthogonal random matrices (GORM). The effec…
Quantum master equation for a system influencing its environment
M. Esposito, P. Gaspard
A perturbative quantum master equation is derived for a system interacting with its environment, which is more general than the ones derived before. Our master equation takes into…
Spectral Characterization of Anomalous Diffusion of a Periodic Piecewise Linear Intermittent Map
S. Tasaki, P. Gaspard
For a piecewise linear version of the periodic map with anomalous diffusion, the evolution of statistical averages of a class of observables with respect to piecewise constant init…
