Abstract

The description of dissipative processes in quantum mechanics here presented is based on the existence of a time operator canonically conjugate to the Liouville operator. The entropy can be defined as a functional of this time operator and a new dissipative semi-group of time evolution can be constructed. This formalism seems well adapted to the description of the decay phenomena and the measurement process.
