Fast vacuum decay into particle pairs in strong electric and magnetic fields
Yoshimasa Hidaka, Takumi Iritani, Hideo Suganuma
We discuss fermion pair productions in strong electric and magnetic fields. We point out that, in the case of massless fermions, the vacuum persistency probability per unit time an…
Spectral Function of Fermion Coupled with Massive Vector Boson at Finite Temperature in Gauge Invariant Formalism
Daisuke Satow, Yoshimasa Hidaka, Teiji Kunihiro
We investigate spectral properties of a fermion coupled with a massive gauge boson with a mass m at finite temperature (T) in the perturbation theory. The massive gauge boson is in…
How Wide is the Transition to Deconfinement?
Adrian Dumitru, Yun Guo, Yoshimasa Hidaka +2
Pure SU(3) glue theories exhibit a deconfining phase transition at a nonzero temperature, Tc. Using lattice measurements of the pressure, we develop a simple matrix model to descri…
Model study of the sign problem in the mean-field approximation
Kenji Fukushima, Yoshimasa Hidaka
We argue the sign problem of the fermion determinant at finite density. It is unavoidable not only in Monte-Carlo simulations on the lattice but in the mean-field approximation as…
