Classification of Non-Abelian Chern-Simons Vortices [article]

Gerald Dunne
1993 arXiv   pre-print
The two-dimensional self-dual Chern-Simons equations are equivalent to the conditions for static, zero-energy vortex-like solutions of the (2+1) dimensional gauged nonlinear Schrödinger equation with Chern-Simons  ...  The Uhlenbeck-Wood classification of such harmonic maps into the unitary groups thereby leads to a complete classification of the vacuum states of the Chern-Simons model.  ...  vortex solution (13) to the self-dual Chern-Simons equations (5, 6) .  ...

Finite Temperature Chern-Simons Coefficient

Gerald Dunne, Kimyeong Lee, Changhai Lu
1997 Physical Review Letters  
We compute the exact finite temperature effective action in a 0+1-dimensional field theory containing a topological Chern-Simons term, which has many features in common with 2+1-dimensional Chern-Simons  ...  2A, the fermion mass term and the Chern-Simons term are not invariant.  ...  (Recall that it is possible to define a Chern-Simons term in odd dimensional space-time. Some features of "Chern-Simons quantum mechanics" have been studied previously [14] .)  ...

Chern-Simons solitons, Toda theories and the chiral model

Gerald Dunne
1992 Communications in Mathematical Physics  
The two-dimensional self-dual Chern--Simons equations are equivalent to the conditions for static, zero-energy solutions of the (2+1)-dimensional gauged nonlinear Schrödinger equation with Chern--Simons  ...  In this paper we classify all finite charge SU(N) solutions by first transforming the self-dual Chern--Simons equations into the two-dimensional chiral model (or harmonic map) equations, and then using  ...  nonlinear Schrödinger equation with Chern-Simons coupling.  ...

Renormalization in coupled-abelian self-dual Chern-Simons models

Gerald Dunne, Theodore Hall
1997 Physics Letters B  
An algebraic restriction of the nonabelian self-dual Chern-Simons-Higgs systems leads to coupled-abelian self-dual models with intricate mass spectra.  ...  In this paper we compute the gauge-gauge-Higgs couplings in the broken phases and use this to compute the finite renormalizations of the Chern-Simons coefficient in the various vacua.  ...  these self-dual Chern-Simons models [15] .  ...

Magnetic symmetries and vortices in Chern-Simons theories

Gerald Dunne, Alex Kovner, Bayram Tekin
2000 Physical Review D, Particles and fields  
We study the locality properties of the vortex operators in compact U(1) Maxwell-Chern-Simons and SU(N) Yang-Mills-Chern-Simons theories in 2+1 dimensions.  ...  Compact QED with the Chern Simons term.  ...  Including the Chern-Simons term does not alter the classical compact gauge symmetries of the system, but we might expect new behavior because the Chern-Simons term generates massive gauge degrees of freedom  ...

Integer quantization of the Chern-Simons coefficient in a broken phase

Lusheng Chen, Gerald Dunne, Kurt Haller, Edwin Lim-Lombridas
1995 Physics Letters B  
Recently there has been some question concerning the renormalization of the Chern-Simons coefficient in such a broken phase.  ...  We show that, in this broken vacuum, the renormalized ratio of the Chern-Simons coupling to the gauge coupling is shifted by 1/4π times an integer, preserving the usual integer quantization condition on  ...  Chern-Simons coupling constant, m [1] .  ...
