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…

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 Ünsal

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 $g cd (N, p) = 1$ …
