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,…

Subdynamics theory in the functional approach to quantum mechanics
Roberto Laura, Rodolfo M. Id Betan
The formalism of subdynamics is extended to the functional approach of quantum systems, and used for the Friedrichs model, in which diagonal singularities in states and observables…
