Non-Abelian Landau-Ginzburg Theory of Ferromagnetic Superconductivity and Photon-Spinon Mixing
Y. M. Cho, Franklin H. Cho
We propose an effective theory of non-Abelian superconductivity, an SU(2)xU(1) extension of the Abelian Landau-Ginzburg theory, which could be viewed as an effective theory of ferr…
D-type Vortex and N-type Vortex in Two-gap Superconductor
Y. M. Cho, Pengming Zhang
We show that the two-gap superconductor has two types of non-Abrikosov magnetic vortex, the D-type which has no concentration of the condensate at the core and the N-type which has…
Non-Abrikosov Vortex and Topological Knot in Two-gap Superconductor
Y. M. Cho, Pengming Zhang
We establish the existence of topologically stable knot in two-gap superconductor whose topology is fixed by the Chern-Simon index of the electromagnetic potential. We p…
Non-Abelian Vortices in Condensed Matter Physics
Y. M. Cho, Hyojoong Khim, Namsik Yong
We study the non-Abelian topological vortices in condensed matter physics, whose topological flux quantum number is described by , not by . We present two examp…
Non-Abelian Superconductivity
Y. M. Cho
We establish a non-Abelian superconductivity and a non-Abelian Meissner effect by constructing an effective field theory of superconductivity in which a genuine SU(2) gauge symmetr…
