Two phonon induced single particle widths in thermally excited Fermion matter

The broadening of single-fermion levels in a heat reservoir where two quantal harmonic vibrations have been located is examined. The oscillations are assumed to couple to the fermionic system and to directly among themselves. The equations of motion of both the macroscopic and the microscopic coordi...
