Phases of the $q$ -deformed $SU (N)$ Yang-Mills theory at large $N$

Tomoya Hayata, Yoshimasa Hidaka, Hiromasa Watanabe

We investigate the $(2 + 1)$ -dimensional $q$ -deformed $SU (N)_{k}$ Yang-Mills theory in the lattice Hamiltonian formalism, which is characterized by three parameters: the numbe…

Deconfinement-Higgs continuity in $SU (2)$ adjoint Higgs model at finite temperature

Yui Hayashi, Masashi Kawahira, Hiromasa Watanabe

We study the finite-temperature phase structure of the four-dimensional $SU (2)$ adjoint Higgs model, focusing on a possible \textit{deconfinement-Higgs continuity}: the conje…

Lattice gradient flows (de-)stabilizing topological sectors

Yuya Tanizaki, Akio Tomiya, Hiromasa Watanabe

We investigate the stability of topological charge under gradient flow taking the admissibility condition into account. For the $S U (2)$ Wilson gauge theory with $β = 2.45$ and $L^4=1…

Toward the application of large- $N$ deconfinement to SU(3) QCD

Hiromasa Watanabe

It is generally known for $U (N)$ gauge theory at finite temperature that phase transitions are manifested by taking the large- $N$ limit. Since the large- $N$ theory undergo…

Non-supersymmetric duality cascade of QCD(BF) via semiclassics on $R^{2} \times T^{2}$ with the baryon-'t Hooft flux

Yui Hayashi, Yuya Tanizaki, Hiromasa Watanabe

We study the phase diagrams of the bifundamental QCD (QCD(BF)) of different ranks, which is the $4$ d $S U (N_{1}) \times S U (N_{2})$ gauge theory coupled with a bifundamental Dirac fermio…
