Decoherence in non integrable systems
Mario Castagnino
Self-induced decoherence formalism and the corresponding classical limit are extended from quantum integrable systems to non-integrable ones.
The role of self-induced decoherence in the problem of the classical limit of quantum mechanics
Mario Castagnino, Manuel Gadella
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…
Gamow Functionals on Operator Algebras
M. Castagnino, M. Gadella, R. Id Betan +1
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,…
Functional approach to quantum decoherence and the classical final limit II: the pointer basis and the quantum measurements
M. Castagnino, R. Laura, R. Id Betan
A quantum system with discrete and continuos evolution spectrum is studied. A final pointer basis is found, that can be defined in a presised mathematical way. This result is use t…
A unified (classical-quantum-statistical) formalism for continuous spectrum systems
Mario Castagnino
A unified (classical-quantum-statistical) formalism for a system with continuous spectrum is introduced. For this kind of systems ergodicity behavior and the existence of microcano…
Decoherence and the Final Pointer Basis
Mario Castagnino, Roberto Laura
Using a functional method it is demonstrated that a generic quantum system evolves to a decohered state in a final pointer basis.
