Magnetic Q-balls

A. J. Balseyro Sebastian, Keisuke Ohashi, Muneto Nitta

We study charged soliton branches in quasi-one-dimensional chiral magnetic systems with Dzyaloshinskii--Moriya (DM) interaction, easy-axis anisotropy, and Zeeman coupling. The same…

Non-Abelian vortices in gauge theory and non-invertible symmetries

Yoshihiko Abe, Tetsutaro Higaki, Kazuya Murakami +2

We construct finite-tension non-Abelian vortex solutions in a renormalizable -dimensional gauge theory Higgsed to the tetrahedral group by a Higgs field in the…

Fractional instantons in 2d 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 nonlinear sigma model on a two-dimensional torus under various shift-c…

Chiral non-Abelian vortex molecules in dense QCD

Sven Bjarke Gudnason, Muneto Nitta

The color-flavor locked phase of high density QCD admits non-Abelian vortices, that are superfluid vortices with confined color-magnetic fluxes. Vortex solutions were thus far cons…

Moduli Spaces of Instantons in Flag Manifold Sigma Models -- Vortices in Quiver Gauge Theories

Toshiaki Fujimori, Muneto Nitta, Keisuke Ohashi

In this paper, we discuss lumps (sigma model instantons) in flag manifold sigma models. In particular, we focus on the moduli space of BPS lumps in general Kähler flag manifold sig…

Chiral Magnets from String Theory

Yuki Amari, Muneto Nitta

Chiral magnets with the Dzyaloshinskii-Moriya (DM) interaction have received quite an intensive focus in condensed matter physics because of the presence of a chiral soliton lattic…
