Abstract

Irreversible transitions are studied in the Wigner representation. When Fermi Golden Rule (FGR) applies, the transition rate is given by the phase-space overlap integral between the initial Wigner function and the final quasi-distribution which is the Wigner transform of the microcanonical density matrix. Classical approximations and various applications are discussed.
