Josephson instantons and Josephson monopoles in a non-Abelian Josephson junction

Non-Abelian Josephson junction is a junction of non-Abelian color superconductors sandwiching an insulator, or non-Abelian domain wall if flexible, whose low-energy dynamics is described by a $U(N)$…

Field theoretical model of multilayered Josephson junction and dynamics of Josephson vortices

Multilayered Josephson junctions are modeled in the context of a field theory, and dynamics of Josephson vortices trapped inside insulators are studied. Starting from a theory consisting of complex…

The DC Josephson effect is the flow of supercurrent across a weak link between two superconductors with different values of their order parameters, the phase. We formulate this notion for any kind…

Topological defects in the Georgi-Machacek model

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 find a possibility of…

Fluctuation modes in multi-gap superonductivity and theory of spontaneous symmetry

We discuss the Nambu-Goldstone boson and the WardTakahashi identity in a system with spontaneous symmetry breaking. We give a formula for the Nambu-Goldstone boson for a general transformation group…

Relations among topological solitons

We clarify relations among topological solitons in various dimensions: a domain wall, non-Abelian vortex, magnetic monopole and Yang-Mills instanton, together with a (non-Abelian) sine-Gordon…

Monopole Josephson Effects in a Dirac Spin Liquid

: Dirac Spin liquids (DSLs) are gapless featureless states, yet interesting by virtue of the effective field theory describing them - (2+1)-dimensional quantum electrodynamics (QED 3 ). Further, a DSL…

BPS pion domain walls in the supersymmetric chiral Lagrangian

We construct exact solutions of BPS pion domain walls in the four-dimensional $\mathcal{N}=1$ supersymmetric SU(N) chiral Lagrangian with pion masses introduced via linear and quadratic…

Domain-wall skyrmions in chiral magnets

Domain wall skyrmions are skyrmions trapped inside a domain wall. We investigate domain wall skyrmions in chiral magnets using a fully analytic approach. Treating the Dzyaloshinskii-Moriya (DM)…

Vortices and Other Topological Solitons in Dense Quark Matter

In this review, we discuss various properties of topological solitons in dense QCD matter, with a particular emphasis on the CFL phase exhibiting superfluidity and superconductivity, and their…

Domain walls and vortices in chiral symmetry breaking

We study domain walls and vortices in chiral symmetry breaking in a QCD-like theory with N flavors in the chiral limit. If the axial anomaly is absent, there exist stable Abelian axial vortices…

Non-Abelian strings in high-density QCD: Zero modes and interactions

The most fundamental strings in high-density color superconductivity are the non-Abelian semisuperfluid strings which have color-gauge flux tubes but behave as superfluid vortices in the energetic…

Phase Instability in Multi-band Superconductors

When a superconductor has multiple bands and there is a phase difference of π between Δ 1 and Δ 2 where Δ i is a gap parameter on a band indexed by i , the junction formed with another superconductor…

Josephson vortex between two atomic Bose-Einstein condensates

The Josephson vortex (JV) between two long parallel coupled atomic Bose-Einstein condensates (BECs) is considered analytically and numerically in the quasi-one-dimensional limit. Its closed…

Vortices, instantons and branes

The purpose of this paper is to describe a relationship between the moduli space of vortices and the moduli space of instantons. We study charge vortices in Yang-Mills-Higgs theories and show that…

Instabilities of non-abelian vortices in dense QCD.

We construct a low-energy effective theory describing non-abelian vortices in the color superconducting quark matter under stress. We demonstrate that all the vortices are radically unstable against…
