A formula for the spectral projection of the time operator
Maurice Courbage, Seyed Majid Saberi Fathi
In this paper, we study the one-level Friedrichs model with using the quantum time super-operator that predicts the excited state decay inside the continuum. Its survival probabili…

Semi-groups and time operators for quantum unstable systems
Maurice Courbage
We use spectral projections of time operator in the Liouville space for simple quantum scattering systems in order to define a space of unstable particle states evolving under a co…
