Gauge Invariance and Stability of SNO vacuum in QCD
Y. M. Cho
We point out a critical defect in the calculation of the functional determinant of the gluon loop in the Savvidy-Nielsen-Olesen (SNO) effective action. We prove that the gauge inva…
Knot Topology of QCD Vacuum
Y. M. Cho
We show that one can express the knot equation of Skyrme theory completely in terms of the vacuum potential of SU(2) QCD, in such a way that the equation is viewed as a generalized…
Vorticity Knot in Two-component Bose-Einstein Condensates
Y. M. Cho
We demonstrate the existence of the helical vortex solution in two-component Bose-Einstein condensates which can be identified as a twisted vorticity flux. Based on this we argue t…
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…
Chromoelectric Knot in QCD
Y. M. Cho
We argue that the Skyrme theory describes the chromomagnetic (not chromoelectric) dynamics of QCD. This shows that the Skyrme theory could more properly be interpreted as an effect…
New Interpretation of Skyrme Theory
Y. M. Cho, B. S. Park, P. M. Zhang
Based on the proposal that the Skyrme theory is a theory of monopole we provide a new interpretation of Skyrme theory, that the theory can also be viewed as an effective theory of…
