Self-induced decoherence: a new approach

M Castagnino, O Lombardi - Studies in History and Philosophy of Science …, 2004 - Elsevier
According to Zurek, decoherence is a process resulting from the interaction between a
quantum system and its environment; this process singles out a preferred set of states …

An Algebraic Model for Quantum Unstable States

S Fortin, M Gadella, F Holik, JP Jorge, M Losada - Mathematics, 2022 - mdpi.com
In this review, we present a rigorous construction of an algebraic method for quantum
unstable states, also called Gamow states. A traditional picture associates these states to …

Decoherence time in self-induced decoherence

M Castagnino, O Lombardi - Physical Review A—Atomic, Molecular, and …, 2005 - APS
A general method for obtaining the decoherence time in self-induced decoherence is
presented. In particular, it is shown that such a time can be computed from the poles of the …

Gamow functionals on operator algebras

M Castagnino, M Gadella, RI Betan… - Journal of Physics A …, 2001 - iopscience.iop.org
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 …

The problem of the classical limit of quantum mechanics and the role of self-induced decoherence

M Castagnino, M Gadella - Foundations of Physics, 2006 - Springer
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 …

New bases for a general definition for the moving preferred basis

M Castagnino, S Fortin - Modern Physics Letters A, 2011 - World Scientific
One of the challenges of the Environment-Induced Decoherence (EID) approach is to
provide a simple general definition of the moving pointer basis or moving preferred basis. In …

Non-Hermitian Hamiltonians in decoherence and equilibrium theory

M Castagnino, S Fortin - Journal of Physics A: Mathematical and …, 2012 - iopscience.iop.org
There are many formalisms to describe quantum decoherence. However, many of them give
a non-general and ad hoc definition of'pointer basis' or'moving preferred basis', and this fact …

Time's arrow and irreversibility in time‐asymmetric quantum mechanics

M Castagnino, M Gadella… - International Studies in the …, 2005 - Taylor & Francis
The aim of this paper is to analyze time‐asymmetric quantum mechanics with respect to the
problems of irreversibility and of time's arrow. We begin with arguing that both problems are …

[HTML][HTML] Residues of the S-matrix for several α12C resonances from the Jost function analysis

P Vaandrager, SA Rakityansky - Nuclear Physics A, 2019 - Elsevier
Parameters of the O 16 resonances 0+, 1−, 2+, 3−, and 4+ as well as the corresponding
residues of the S-matrix are extracted from experimental data on elastic α 12 C scattering …

The gamow functional

M Castagnino, M Gadella, RI Betán, R Laura - Physics Letters A, 2001 - Elsevier
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 …
