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…
Global time asymmetry as a consequence of a wave packets theorem
Mario A. Castagnino, Jorge Gueron, Adolfo Ordoniez
When any wave packet in the liouvillian representation of the density matrices, becomes a Hardy class function from below. This fact, in the global frame of Reichenb…
A general mathematical structure for the time-reversal operator
Mario Alberto Castagnino, Adolfo Ramon Ordoniez, Daniela Beatriz Emmanuele
The aim of this work is the mathematical analysis of the physical time-reversal operator and its definition as a geometrical structure\QTR{bf}{, }in such a way that it could be gen…
