  • Damping rate of a massive fermion in a hot medium 
    Henning, P.A. (Condensed Matter Physics, 2000)
    In a hot system every excitation acquires a finite lifetime, manifesting itself in a non-zero spectral width. Ordinary damping as well as quantum memory effects arise from this nontrivial spectral function. This report ...
