Abe homotopy classification of topological excitations under the topological influence of vortices
Shingo Kobayashi, Michikazu Kobayashi, Yuki Kawaguchi +2
Topological excitations are usually classified by the th homotopy group . However, for topological excitations that coexist with vortices, there are case in which an elemen…
Vortices on Orbifolds
Taro Kimura, Muneto Nitta
The Abelian and non-Abelian vortices on orbifolds are investigated based on the moduli matrix approach, which is a powerful method to deal with the BPS equation. The moduli space a…
Dirac returns: non-Abelian statistics of vortices with Dirac fermions
Shigehiro Yasui, Kazunori Itakura, Muneto Nitta
Topological superconductors classified as type D admit zero-energy Majorana fermions inside vortex cores, and consequently the exchange statistics of vortices becomes non-Abelian,…
Vortices and Monopoles in Mass-deformed SO and USp Gauge Theories
Minoru Eto, Toshiaki Fujimori, Sven Bjarke Gudnason +4
Effects of mass deformations on 1/2 Bogomol'nyi-Prasad-Sommerfield (BPS) non-Abelian vortices are studied in 4d N=2 supersymmetric U(1) \times SO(2n) and U(1) \times USp(2n) gauge…
Decomposing Instantons in Two Dimensions
Muneto Nitta, Walter Vinci
We study BPS string-like solutions in the 3+1 dimensional gauged CP(1) non-linear sigma model. The same analysis can be applied to study instantons in 2 euclidean dimensions. We us…
Index theorem and Majorana zero modes along a non-Abelian vortex in a color superconductor
Takanori Fujiwara, Takahiro Fukui, Muneto Nitta +1
Color superconductivity in high density QCD exhibits the color-flavor locked (CFL) phase. To explore zero modes in the CFL phase in the presence of a non-Abelian vortex with an SU(…
