Primordial neutron star; a new candidate of dark matter
M. Yoshimura
Z-boson exchange interaction induces attractive force between left-handed neutrino and neutron. The Ginzburg-Landau mean field calculation and the Bogoliubov transformation suggest…
New types of instability and CP violation in electroweak theory
M. Yoshimura
It is known that the Schwinger mechanism of vector-like QED theory is afflicted by a logarithmic singularity under background electromagnetic field due to a hypothetical massless c…
B L genesis by sliding inflaton
M. Yoshimura
We propose a new mechanism of lepton (L) number asymmetry generation, hence offer an explanation of matter-antimatter imbalance when a significant amount of baryon number is later…
Time Evolution of Tunneling in Thermal Medium -- Environment-driven Excited Tunneling --
Sh. Matsumoto, M. Yoshimura
Time evolution of tunneling phenomena proceeding in thermal medium is studied using a standard model of environment interaction. A semiclassical probability formula for the particl…
Tunneling Phenomena in Cosmology: Some Fundamental Problems
M. Yoshimura
The fundamental problem of how tunneling in thermal medium is completed is addressed, and a new time scale of order 1/friction for its termination, which is usually much shorter th…
Quantum tunneling in thermal medium
Sh. Matsumoto, M. Yoshimura
Time evolution of tunneling phenomena in medium is studied using a standard model of environment interaction. A semiclassical formula valid at low, but finite temperatures is deriv…
