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…

Dynamics of Subcritical Bubbles in First Order Phase Transition

Tetsuya Shiromizu, Masahiro Morikawa, Jun'ichi Yokoyama

We derivate the Langevin and the Fokker-Planck equations for the radius of O(3)-symmetric subcritical bubbles as a phenomenological model to treat thermal fluctuation. The effect…

Thermal fluctuations in electroweak phase transition

Tetsuya Shiromizu, Masahiro Morikawa, Jun'ichi Yokoyama

We estimate the amplitude of thermal fluctuations by calculating the typical size of subcritical bubbles in cosmological electroweak phase transition and show that this thermal flu…
