Quantum Probability and Infinite Dimensional Analysis, 2010
In the evolution of a quantum system subject to a nonlinear dissipative term of Kostin type the probability amplitudes associated to excited states of the Hamiltonian are damped; this results in a dynamic convergence toward the ground state. In this paper we dicuss how dissipation can replace adiabatic evolution in the search of the ground state of a ...

Quantum reflection and dissipation
Physical Review B, 1987The effect of dissipation on quantum reflection is treated in the weak-coupling limit. For high incident energies, dissipation suppresses quantum reflection. Surprisingly, for intermediate incident energies, the reflection rate is greatly enhanced because of energy fluctuations. The reflection rate increases with temperature as exp(${T}^{n}$), with the

Physica Scripta, 1987
Summary: A report is presented on recent work on chaos and the onset of chaos in dissipative quantized systems described by discrete maps. The method of quantization of such maps is described, and the formulation of the quantized maps -- conservative or dissipative -- in terms of `quasistochastic' \(c\)-number maps explained.

The talk reviews some recent developments in the theory of quantum mechanical tunneling. The new phenomena discussed arise from the coupling of the tunneling system to a heat bath of temperature T. The question is how dissipation and thermal fluctuation affect the tunneling rate.

Complex biological systems, like the photosynthetic units of bacteria or plants, usually consist of several pigment molecules, which form aggregates, embedded in a protein environment. Within a quantum mechanical treatment it is practically impossible to take all degrees of freedom (DOFs) of such large systems explicitly into account.

Our discussion so far has been restricted to classical dissipative systems. We now turn our attention to systems which are quantum mechanical, and yet are in contact with a heat bath which injects dissipation. Quantum mechanics introduces additional frequency scales in the problem through deterministic evolution. The interplay of these frequencies with

Anisotropy dissipation in quantum cosmology
Physical Review D, 1991We study the issue of decoherence and dissipation in the wave function of the Universe for a Bianchi type-I universe with classical and quantum matter. We obtain a coarse-grained description by tracing over the matter degrees of freedom. Provided that for small universes the wave function of the universe is concentrated on a neighborhood of the ...
