Emergent discrete 3-form symmetry and domain walls
Yoshimasa Hidaka, Muneto Nitta, Ryo Yokokura
We show that axion models with the domain wall number in dimensions, i.e., periodic scalar field theories admitting axion domain walls, exhibit an emergent ${\mathb…
Topology change from a monopole to a dipole in Berry's phase
Shinichi Deguchi, Kazuo Fujikawa
The smooth topology change of Berry's phase from a Dirac monopole-like configuration to a dipole configuration, when one approaches the monopole position in the parameter space, is…
Fractional angle, 't Hooft anomaly, and quantum instantons in charge- multi-flavor Schwinger model
Tatsuhiro Misumi, Yuya Tanizaki, Mithat Ünsal
This work examines non-perturbative dynamics of a -dimensional QFT by using discrete 't Hooft anomaly, semi-classics with circle compactification and bosonization. We focus on c…
Phase structure of the twisted flag sigma model on
Masaru Hongo, Tatsuhiro Misumi, Yuya Tanizaki
We investigate the phase structure of the compactified -dimensional nonlinear flag sigma model with respect to two -terms. Based on the circle compactification…
Fate of spin polarization in a relativistic fluid: An entropy-current analysis
Koichi Hattori, Masaru Hongo, Xu-Guang Huang +2
We derive relativistic hydrodynamic equations with a dynamical spin degree of freedom on the basis of an entropy-current analysis. The first and second laws of local thermodynamics…
