Abelian and Non-Abelian Monopole Configuration in Condensed Matters
Yunkyu Bang, Y. M. Cho, Tieyan Si +1
We discuss the Abelian and non-Abelian monopoles which could exist in condensed matters. We show how the Dirac monopole can be regularized by the charge screening, and argue that t…
Regularization of Electroweak Monopole by Charge Screening and BPS Energy Bound
Pengming Zhang, Li-Ping Zou, Y. M. Cho
We show that the electroweak monopole can be regularized with a non-vacuum electromagnetic permittivity. This allows us to set a new BPS bound for the monopole mass, which implies…
Re-interpretation of Skyrme Theory: New Topological structures
Pengming Zhang, Kyoungtae Kimm, Liping Zou +1
Recently it has been pointed out that the skyrmions carry two independent topology, the baryon topology and the monopole topology. We provide more evidence to support this. In spec…
On finite energy monopole solutions in Weinberg-Salam model
D. G. Pak, P. M. Zhang, L. P. Zou
We study the problem of existence of finite energy monopole solutions in the Weinberg-Salam model starting with a most general ansatz for static axially-symmetric electroweak magne…
Monopoles without magnetic charges: Finite energy monopole-antimonopole configurations in CP1 model and restricted QCD
L. P. Zou, P. M. Zhang, D. G. Pak
We propose a new type of regular monopole-like field configuration in quantum chromodynamics (QCD) and CP^1 model. The monopole configuration can be treated as a monopole-antimonop…
Separability and Dynamical Symmetry of Quantum Dots
P. -M. Zhang, L. -P. Zou, P. A. Horvathy +1
The separability and Runge-Lenz-type dynamical symmetry of the internal dynamics of certain two-electron Quantum Dots, found by Simonović et al. [1], is traced back to that of the…
Exact knot solutions in a generalized Skyrme-Faddeev model
L. P. Zou, P. M. Zhang, D. G. Pak
We propose a generalized Skyrme-Faddeev type theory with an additional scalar field. In a special case of model parameters one has a theory which admits exact knot solutions given…
Knot topology in QCD
L. P. Zou, P. M. Zhang, D. G. Pak
We consider topological structure of classical vacuum solutions in quantum chromodynamics. Topologically non-equivalent vacuum configurations are classified by non-trivial second a…
Weyl symmetric structure of QCD vacuum
Y. M. Cho, D. G. Pak, P. M. Zhang +1
We consider Weyl symmetric structure of the classical vacuum in quantum chromodynamics. In the framework of formalism of gauge invariant Abelian projection we show that classical v…
