Phase Structures of SU(N) Gauge-Higgs Models on Multiply Connected Spaces

Hisaki Hatanaka, Katsuhiko Ohnishi, Makoto Sakamoto +1

We study an SU(N) gauge-Higgs model with N_F massless fundamental fermions on M^3 \otimes S^1. The model has two kinds of order parameters for gauge symmetry breaking: the componen…

Multi-phases in gauge theories on non-simply connected spaces

Hisaki Hatanaka, Katsuhiko Ohnishi, Makoto Sakamoto +1

It is pointed out that phase structures of gauge theories compactified on non-simply connected spaces are not trivial. As a demonstration, an SU(2) gauge model on …

Vacuum Structure of Twisted Scalar Field Theories on M^{D-1} \otimes S^1

H. Hatanaka, S. Matsumoto, K. Ohnishi +1

We study scalar field theories on M^{D-1} \otimes S^1, which allow to impose twisted boundary conditions for the S^1 direction, in detail and report several interesting properties…

Symmetry Breaking/Restoration in a Non-Simply Connected Space-Time

Hisaki Hatanaka, Seiho Matsumoto, Katsuhiko Ohnishi +1

Field theories compactified on non-simply connected spaces, which in general allow to impose twisted boundary conditions, are found to unexpectedly have a rich phase structure. One…

Novel Phase Structure of Twisted O(N) phi^4 model on M^D-1 \times S^1

Katsuhiko Ohnishi, Makoto Sakamoto

We study the O(N) model compactified on , which allows to impose twisted boundary conditions for the -direction. The O(N) symmetry can be broken to $…
