Monopoles, Center Vortices, Confinement in (3+1)d, and the Lens-Space Twisted Partition Function

Yui Hayashi, Yuya Tanizaki

We propose the gauge-invariant criteria of center-vortex condensation and monopole condensation using the $Z_{N}^{[1]}$ -symmetry twisted partition functions: The torus twist…

Wilson-'t Hooft classification and the perimeter law for dyonic loops in 3d monopole semiclassics

Yui Hayashi, Yuya Tanizaki

We investigate the long-distance behavior of dyonic loop operators in 4d $S U (N)$ gauge theories on $R^{3} \times S^{1}$ using the 3d monopole semiclassics. If we employ the na…

Center-vortex semiclassics with non-minimal 't Hooft fluxes on $R^{2} \times T^{2}$ and center stabilization at large $N$

Yui Hayashi, Yuya Tanizaki, Mithat Ãnsal

We consider the semiclassical description of confinement for $4$ d $S U (N)$ Yang-Mills theory on small $R^{2} \times T^{2}$ with non-minimal 't Hooft twist $p$ with $g cd (N, p) = 1$ …

Fractional instantons in 2d $C P^{N - 1}$ model and 4d Yang-Mills theory with 't Hooft twists

Yui Hayashi, Tatsuhiro Misumi, Muneto Nitta +2

We derive the explicit formula for fractional BPS lumps (or fractional instantons) in the $C P^{N - 1}$ nonlinear sigma model on a two-dimensional torus under various shift-c…

Monopole-vortex continuity of $N = 1$ super Yang-Mills theory on $R^{2} \times S^{1} \times S^{1}$ with 't Hooft twist

Yui Hayashi, Tatsuhiro Misumi, Yuya Tanizaki

We study $N = 1$ $S U (N)$ super Yang-Mills (SYM) theory on $R^{2} \times (S^{1})_{3} \times (S^{1})_{4}$ with the 't Hooft twist. The theory becomes weakly coupled if the le…
