Lattice study on the twisted $C P^{N - 1}$ models on $R \times S^{1}$

Tatsuhiro Misumi, Toshiaki Fujimori, Etsuko Itou +2

We report the results of the lattice simulation of the $C P^{N - 1}$ sigma model on $S_{s}^{1}$ (large) $\times$ $S_{τ}^{1}$ (small). We take a sufficiently large ratio of the…

Lattice gauge theory for Haldane conjecture and central-branch Wilson fermion

Tatsuhiro Misumi, Yuya Tanizaki

We develop the $(1 + 1)$ d lattice $U (1)$ gauge theory in order to define $2$ -flavor massless Schwinger model, and discuss its connection with Haldane conjecture. We propose to use th…

Confinement-Deconfinement Crossover in the Lattice $C P^{N - 1}$ Model

Toshiaki Fujimori, Etsuko Itou, Tatsuhiro Misumi +2

The $C P^{N - 1}$ sigma model at finite temperature is studied using lattice Monte Carlo simulations on $S_{s}^{1} \times S_{τ}^{1}$ with radii $L_{s}$ and $L_{τ}$ , respectively,…

Instantons in Chiral Magnets

Masaru Hongo, Toshiaki Fujimori, Tatsuhiro Misumi +2

We exhaustively construct instanton solutions and elucidate their properties in one-dimensional anti-ferromagnetic chiral magnets based on the $O (3)$ nonlinear sigma model descript…

Fractional $θ$ angle, 't Hooft anomaly, and quantum instantons in charge- $q$ multi-flavor Schwinger model

Tatsuhiro Misumi, Yuya Tanizaki, Mithat Ünsal

This work examines non-perturbative dynamics of a $2$ -dimensional QFT by using discrete 't Hooft anomaly, semi-classics with circle compactification and bosonization. We focus on c…

Phase structure of the twisted $S U (3) / U (1)^{2}$ flag sigma model on $R \times S^{1}$

Masaru Hongo, Tatsuhiro Misumi, Yuya Tanizaki

We investigate the phase structure of the compactified $2$ -dimensional nonlinear $S U (3) / U (1)^{2}$ flag sigma model with respect to two $θ$ -terms. Based on the circle compactification…
