The Definition of Entropy for Quantum Unstable Systems: A View-Point Based on the Properties of Gamow States

In this paper, we review the concept of entropy in connection with the description of quantum unstable systems. We revise the conventional definition of entropy due to Boltzmann and extend it so as to include the presence of complex-energy states. After introducing a generalized basis of states whic...
