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…
Reinterpretation of Faddeev-Niemi Knot in Skyrme Theory
Y. M. Cho
We identify the Faddeev-Niemi knot in Skyrme theory as a vortex ring made of a helical baby skyrmion (a twisted chromomagnetic vortex which is periodic in -coodinate) with the 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…
Cho and Pak reply to Lamm et al. comment on "A Convergent Series for the QED Effective Action"
Y. M. Cho
Cho and Pak reply to Lamm et al. [hep-th/0007108] comment on "A Convergent Series for the Effective Action of QED" [hep-th/0006057].
Color Reflection Invariance and Monopole Condensation in QCD
Y. M. Cho
We review the quantum instability of the Savvidy-Nielsen-Olesen (SNO) vacuum of the one-loop effective action of SU(2) QCD, and point out a critical defect in the calculation of th…
