Aharonov-Bohm phase in high density quark matter

C Chatterjee, M Nitta - Physical Review D, 2016 - APS
Stable non-Abelian vortices, which are color magnetic flux tubes as well as superfluid
vortices, are present in the color-flavor locked phase of dense quark matter with diquark …

BPS Alice strings

C Chatterjee, M Nitta - Journal of High Energy Physics, 2017 - Springer
A bstract When a charged particle encircles around an Alice string, it changes the sign of the
electric charge. In this paper we find a BPS-saturated Alice string in U (1)× SO (3) gauge …

[HTML][HTML] The effective action of a BPS Alice string

C Chatterjee, M Nitta - The European Physical Journal C, 2017 - Springer
Recently a BPS Alice string has been found in a U (1) * SO (3) U (1)× SO (3) gauge theory
coupled with three charged complex scalar fields in the triplet representation (in JHEP 1709 …

Low-energy effective worldsheet theory of a non-Abelian vortex in high-density QCD revisited: A regular gauge construction

C Chatterjee, M Nitta - Physical Review D, 2017 - APS
Color symmetry is spontaneously broken in quark matter at high density as a consequence
of di-quark condensations with exhibiting color superconductivity. Non-Abelian vortices or …

Aharonov-Bohm defects

C Chatterjee, M Nitta - Physical Review D, 2020 - APS
We discuss what happens when a field that receives an Aharonov-Bohm (AB) phase
develops a vacuum expectation value (VEV), using the example of an Alice string in a U (1)× …

Confinement and moduli locking of Alice strings and monopoles

M Nitta - Journal of High Energy Physics, 2021 - Springer
A bstract We argue that strings (vortices) and monopoles are confined, when fields receiving
nontrivial Aharonov-Bohm (AB) phases around a string develop vacuum expectation values …

Existence of non-Abelian vortices in a coupled 4D-2D quantum field theory

Y Xu, S Chen - arXiv preprint arXiv:2405.07548, 2024 - arxiv.org
Vortices produce locally concentrated field configurations and are solutions to the nonlinear
partial differential equations systems of complicated structures. In this paper, we establish …
