Abstract:In this paper we study fractional as well as semi-local Chern-Simons vortices in G = U (1) × SO(2M ) and G = U (1) × U Sp(2M ) theories. The master equations are solved numerically using appropriate Ansätze for the moduli matrix field. In the fractional case the vortices are solved in the transverse plane due to the broken axial symmetry of the configurations (i.e. they are non-rotational invariant). It is shown that unless the fractional vortex-centers are all coincident (i.e. local case) the ring-like flux s… Show more
“…Motivated by the delicate issue of "'quark confinement"', Gudnason in [33,34] introduced a non-abelian Chern-Simons model formulated within a N = 2 Supersymmetric (SUSY) Field Theory, with a general gauge group of the type: G = U (1) × G ′ allowing solutions with orientational modes. For the model in [33,34], the author identifies the BPS-sector of the theory and the corresponding self-dual equations. In particular, when G ′ = SO (2) or G ′ = U S p (2), Gudnason in [33,34] introduced some meaningful physical ansatz on the structure of the vortex solutions, by which (as in [40]) the corresponding self-dual equations reduced to the following set of Master's equations:…”

“…In this context, a successful way to detect vortices is to identify the BPS-sector of the theory, since in such regime vortex configurations simply correspond to (static) solutions of the so called self-dual equations of Bogomolnyi type, and saturate the minimal energy allowed by the system. For this reason, it has been useful to invoke "duality" and formulate the theory within the general framework of N = 2 Supersymmetric (SUSY) Field Theory, in this direction see for example: [27,28,31,33,34,55,60] for more details . We observe that, when the Chern-Simons Lagrangian is taken into account then the theory can attain self-duality only with the help of a six-order scalar potential field, see [26,67,71], in place of the more familiar quadratic (double-well) potential of the Maxwell-Higgs model, see [40].…”

Motivated by the study of non-abelian Chern Simons vortices of non-topological type in Gauge Field Theory, see e.g. [33,34], [26], we analyse the solvability of the following (normalised) Liouville-type system in presence of singular sources:2π R 2 e u1 and β 2 = 1 2π R 2 e u2 , with τ > 0 and N > 0. We identify necessary and sufficient conditions on the parameter τ and the "flux" pair: (β 1 , β 2 ), which ensure the radial solvability of (1) τ .

Since for τ = 1 2 , problem (1) τ reduces to the (integrable) 2 X 2 Toda system, in particular we recover the existence result of [50] and [41], concerning this case. Our method relies on a blow-up analysis for solutions of (1) τ , which (even in the radial setting) takes new turns compared to the single equation case. We mention that our approach permits to handle also the non-symmetric case, where in each of the two equations in (1) τ , the parameter τ is replaced by two different parameters τ 1 > 0 and τ 2 > 0 respectively, and when also the second equation in (1) τ includes a Dirac measure supported at the origin.

Abstract. We establish a general small data global existence and decay theorem for Chern-Simons theories with a general gauge group, coupled with a massive relativistic field of spin 0 or 1/2. Our result applies to a wide range of relativistic Chern-Simons theories considered in the literature, including the abelian/non-abelian self-dual Chern-Simons-Higgs equation and the Chern-Simons-Dirac equation. A key idea is to develop and employ a gauge invariant vector field method for relativistic Chern-Simons theories, which allows us to avoid the long range effect of charge.
We study fractional Skyrmions in a ℂP2 baby Skyrme model with a generalization of the easy-plane potential. By numerical methods, we find stable, metastable, and unstable solutions taking the shapes of molecules. Various solutions possess discrete symmetries, and the origin of those symmetries are traced back to congruencies of the fields in homogeneous coordinates on ℂP2.
