Warped brane-world compactification with Gauss-Bonnet term
Y. M. Cho, Ishwaree P. Neupane
In the Randall-Sundrum (RS) brane-world model a singular delta-function source is matched by the second derivative of the warp factor. So one should take possible curvature correct…
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…
Knots in Condensed Matters
Y. M. Cho
We propose two types of topologically stable knot solitons in condensed matters, one in two-component Bose-Einstein condensates and one in two-gap superconductors. We identify the…
Monopoles and Knots in Skyrme Theory
Y. M. Cho
We show that the Skyrme theory actually is a theory of monopoles which allows a new type of solitons, the topological knots made of monopole-anti-monopole pair,which is different f…
Electroweak Knot
Y. M. Cho
We demonstrate the existence of stable knot solitons in the standard electroweak theory whose topological quantum number is fixed by the Chern-Simon index of the bos…
Faddeev-Niemi Conjecture and Effective Action of QCD
Y. M. Cho, H. W. Lee, D. G. Pak
We calculate a one loop effective action of SU(2) QCD in the presence of the monopole background, and find a possible connection between the resulting QCD effective action and a ge…
QCD versus Skyrme-Faddeev Theory
W. S. Bae, Y. M. Cho, Sang-Woo Kim
We discuss the physical impacts of the ``Cho decomposition'' (or the ``Cho-Faddeev-Niemi-Shabanov decomposition'') of the non-Abelian gauge potential on QCD. We show how the decomp…
Effective Lagrangian with valence gluons in extended SU(2) QCD model
Y. M. Cho, Haewon Lee, D. G. Pak
The effective action with homogeneous valence (off-diagonal) gluons as background fields in the extended SU(2) model of QCD is obtained in one-loop approximation. We keep the manif…
