The Problem of the Classical Limit of Quantum Mechanics and the Role of Self-Induced Decoherence
- M. Castagnino, M. Gadella
- Mathematics
- 6 September 2006
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 a… Expand
The equilibrium limit of the Casati-Prosen model
- M. Castagnino
- Physics
- 19 March 2006
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
- M. Castagnino, L. Lara, O. Lombardi
- Physics
- 25 November 2002
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 of… Expand
Gamow Functionals on Operator Algebras
- M. Castagnino, M. Gadella, R. I. Betan, R. Laura
- Mathematics, Physics
- 30 November 2001
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 and… Expand
Formal Features of a General Theoretical Framework for Decoherence in Open and Closed Systems
- M. Castagnino, S. Fortin
- Physics, Mathematics
- 5 January 2013
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 Theoretical… Expand
The Formulation of Quantum Mechanics in Terms of Nuclear Algebras
- S. Iguri, M. Castagnino
- Mathematics
- 1999
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 of… Expand
FROM CLASSICAL CHAOS TO DECOHERENCE IN ROBERTSON–WALKER COSMOLOGY
- F. Lombardo, M. Castagnino, L. Bombelli
- Physics
- 25 June 1998
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 and… Expand
The Gamow functional
- M. Castagnino, M. Gadella, R. I. Beta, R. Laura
- Physics
- 23 April 2001
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 other… Expand
On the classical limit of quantum mechanics, fundamental graininess and chaos: Compatibility of chaos with the correspondence principle
- Ignacio S. Gomez, M. Castagnino
- Physics, Mathematics
- 27 September 2010
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. We… Expand
