    "abstract": "We derive dissipative effective Hamiltonian for the unstable Lee model\nwithout any ad hoc coarse graining procedure. Generalized radiative\ncorrections, utilizing the in-in formalism of quantum field theory,\nautomatically yield irreversibility as well as the decay of quantum coherence.\nEspecially we do not need to extend the ordinary Hilbert space for describing\nthe intrinsically dissipative system if we use the generalized in-in formalism\nof quantum field theory.",
