Non Perturbative Destruction of Localization in the Quantum Kicked Particle Problem
Doron Cohen
The angle coordinate of the Quantum Kicked Rotator problem is treated as if it were an extended coordinate. A new mechanism for destruction of coherence by noise is analyzed using…
Chaos, Dissipation and Quantal Brownian Motion
Doron Cohen
Energy absorption by driven chaotic systems, the theory of energy spreading and quantal Brownian motion are considered. In particular we discuss the theory of a classical particle…
Quantal-Classical Duality and the Semiclassical Trace Formula
Doron Cohen, Harel Primack, Uzy Smilansky
We consider Hamiltonian systems which can be described both classically and quantum mechanically. Trace formulas establish links between the energy spectra of the quantum descripti…
Quantum Dissipation versus Classical Dissipation for Generalized Brownian Motion
Doron Cohen
We try to clarify what are the genuine quantal effects that are associated with generalized Brownian Motion (BM). All the quantal effects that are associated with the Zwanzig-Feynm…
Periodic Orbits, Breaktime and Localization
Doron Cohen
The main goal of the present paper is to convince that it is feasible to construct a `periodic orbit theory' of localization by extending the idea of classical action correlations.…
Unified Model for The Study of Diffusion Localization and Dissipation
Doron Cohen
A new model that generalizes the study of quantum Brownian motion (BM) is constructed. We consider disordered environment that may be either static (quenched), noisy or dynamical.…
