Finite density effects in Hosotani mechanism and a vacuum gauge ball
Yoshinori Cho, Kiyoshi Shiraishi
We consider the finite density effects of the fermion with U(1) gauge symmetry in Hosotani mechanism. We construct a vacuum gauge ball, a new kind of non-topological soliton, and i…

One-loop finite potential for N-2 scalars from N quantum fields
Yoshinori Cho, Nahomi Kan, Kenji Sakamoto +1
We study the one-loop effective potential induced from quantum fluctuation of a finite number of fields. A series expansion in terms of the modified Bessel functions is useful to e…
