Non-Abelian strings and domain walls in two Higgs doublet models

M Eto, M Kurachi, M Nitta - Journal of High Energy Physics, 2018 - Springer
A bstract Contrary to the standard model that does not admit topologically nontrivial solitons,
two Higgs doublet models admit topologically stable vortex strings and domain walls. We …

Chiral non-Abelian vortices and their confinement in three flavor dense QCD

M Eto, M Nitta - Physical Review D, 2021 - APS
We find chiral non-Abelian vortices having windings only in one of the diquark
condensations of left-handed and right-handed quarks in the color-flavor locked phase of …

Quark-hadron continuity under rotation: Vortex continuity or boojum?

C Chatterjee, M Nitta, S Yasui - Physical Review D, 2019 - APS
Quark-hadron continuity was proposed as a crossover between hadronic matter and quark
matter without a phase transition, based on the matching of the symmetries and excitations …

Phase transition on superfluid vortices in Higgs-Confinement crossover

T Hayata, Y Hidaka, D Kondo - arxiv preprint arxiv:2411.03676, 2024 - arxiv.org
We propose a novel method to distinguish states of matter by identifying spontaneous
symmetry breaking on extended objects, such as vortices, even in the absence of a bulk …

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 …

Chiral non-Abelian vortex molecules in dense QCD

SB Gudnason, M Nitta - arxiv preprint arxiv:2501.18464, 2025 - arxiv.org
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 …

Quark-Hadron crossover with vortices

C Chatterjee, M Nitta, S Yasui - … of the 8th International Conference on …, 2019 - journals.jps.jp
The quark-hadron crossover conjecture was proposed as a continuity between hadronic
matter and quark matter with no phase transition. It is based on matching of symmetry and …

Topological defects in the Georgi-Machacek model

C Chatterjee, M Kurachi, M Nitta - Physical Review D, 2018 - APS
We study topological defects in the Georgi-Machacek model in a hierarchical symmetry
breaking in which extra triplets acquire vacuum expectation values before the doublet. We …

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 …

Dynamics of global and local vortices with orientational moduli

M Eto, A Peterson, FI Schaposnik Massolo… - Journal of High Energy …, 2021 - Springer
A bstract The dynamics of both global and local vortices with non-Abelian orientational
moduli is investigated in detail. Head-on collisions of these vortices are numerically …
