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 …

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 …

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 …

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 …

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 …

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 …

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 …

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 …

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 …
