Dissipative Quantum Tunneling from Quantum Potential Approach -- Back Reaction of Particle Creation --
Fumiaki Shibata, Masahiro Morikawa, Tetsuya Shiromizu +1
Back reaction of the particle creation on the quantum tunneling process is analyzed in real time formalism. We use quantum potential method in which whole quantum dynamics is exact…

Spontaneous dissipation from generalized radiative corrections
Masahiro Morikawa
We derive dissipative effective Hamiltonian for the unstable Lee model without any ad hoc coarse graining procedure. Generalized radiative corrections, utilizing the in-in formalis…
