The Problem of the Classical Limit of Quantum Mechanics and the Role of Self-Induced Decoherence
Our account of the problem of the classical limit of quantum mechanics involves two elements. The first one is self-induced decoherence, conceived as a process that depends on the own dynamics of aExpand

The equilibrium limit of the Casati-Prosen model
Abstract An alternative explanation of the decoherence in the Casati–Prosen model is presented. It is based on the self-induced decoherence formalism extended to non-integrable systems.

The cosmological origin of time asymmetry
In this paper, we address the problem of the arrow of time from a cosmological point of view, rejecting the traditional entropic approach that defines the future direction of time as the direction ofExpand

Gamow Functionals on Operator Algebras
We obtain the precise form of two Gamow functionals representing the exponentially decaying part of a quantum resonance and its mirror image that grows exponentially, as a linear, positive andExpand

Formal Features of a General Theoretical Framework for Decoherence in Open and Closed Systems
Two complementary decoherence formalisms, Environment Induced Decoherence (EID) for open systems and Self Induced Decoherence (SID) for close systems are compared under a common General TheoreticalExpand

The Formulation of Quantum Mechanics in Terms of Nuclear Algebras
In this work we analyze the convenience ofnuclear barreled b*-algebras as a better mathematicalframework for the formulation of quantum principles thanthe usual algebraic formalism in terms ofExpand

FROM CLASSICAL CHAOS TO DECOHERENCE IN ROBERTSON–WALKER COSMOLOGY
We analyze the relationship between classical chaos and particle creation in Robertson–Walker cosmological models with gravity coupled with a scalar field. Within our class of models chaos andExpand

The Gamow functional
We present a formalism that represents pure states, mixtures and generalized states as functionals on an algebra containing the observables of the system. Along these states, there are otherExpand

On the classical limit of quantum mechanics, fundamental graininess and chaos: Compatibility of chaos with the correspondence principle
Abstract The aim of this paper is to review the classical limit of Quantum Mechanics and to precise the well known threat of chaos (and fundamental graininess) to the correspondence principle. WeExpand
