Quantum transients are temporary features of matter waves before they reach a stationary regime. Transients may arise after the preparation of an unstable initial state or due to a sudden interaction or a change in the boundary conditions.

From a general study of the relations between models, meaning the set of variables with their mathematical properties, and the measures they represent, a new formalism is developed, which covers the scope of Quantum Mechanics.

We revise fundamental concepts in the dynamics of open quantum systems in the light of modern developments in the field. Our aim is to present a unified approach to the quantum evolution of open systems that incorporates the traditional concepts.

An interesting topic of quantum mechanics is the study of open quantum systems. By it, we mean a simple quantum system, described by one or a few degrees of freedom, interacting with a background characterized by a continuum of excitations.
