New gauge-independent transition separating confinement-Higgs phase in the lattice gauge-fundamental scalar model
Ryu Ikeda, Kei-Ichi Kondo, Akihiro Shibata +1
The lattice gauge-scalar model with the scalar field in the fundamental representation of the gauge group has a single confinement-Higgs phase which is well-known as the Fradkin-Sh…
Gauge-independent transition separating confinement and Higgs phases in lattice SU(2) gauge theory with a scalar field in the fundamental representation
Ryu Ikeda, Seikou Kato, Kei-Ichi Kondo +1
According to the preceding studies, the lattice SU(2) gauge-scalar model with a single scalar field in the fundamental representation of the gauge group has a single confinement-Hi…
Magnetic monopole dominance for the Wilson loops in higher representations
Akihiro Shibata, Seikou Kato, Kei-Ichi Kondo
The dual superconductor picture is one of the most promising scenarios for quark confinement. To investigate this picture in a gauge-invariant manner, we have proposed a new formul…
Double-winding Wilson loops in SU(N) lattice Yang-Mills gauge theory
Seikou Kato, Akihiro Shibata, Kei-Ichi Kondo
We study double-winding Wilson loops in lattice Yang-Mills gauge theory by using both strong coupling expansions and numerical simulations. First, we examine how the area l…
Confinement/deconfinement phase transition and dual Meissner effect in SU(3) Yang-Mills theory
Akihiro Shibata, Kei-Ichi Kondo, Seikou Kato
We investigate the confinement-deconfinement phase transition at finite temperature of the SU(3) Yang-Mills(YM) theory on the lattice from a viewpoint of the dual superconductor pi…
Type of dual superconductivity for and Yang--Mills theories
Akihiro Shibata, Kei-Ichi Kondo, Shogo Nishino +2
We investigate the type of dual superconductivity responsible for quark confinement. For this purpose, we solve the field equations of the Abelian--Higgs model to obtain the…
