Gauge Invariance in Chern-Simons Systems
We show explicitly that the question of gauge invariance of the effective
potential in standard scalar electrodynamics remains unchanged despite the
introduction of the Chern-Simons term. The result does not depend on the
presence of the Maxwell term in the Chern-Simons territory.Comment: 10 pages, Plain Tex, DF/UFPB-14/9
Gauge Invariant Effective Potential for Abelian Maxwell-Chern-Simons Systems
We investigate the effective potential for Abelian Maxwell--Chern--Simons
systems. The calculations follow an alternate approach, recently proposed as a
gauge invariant formulation of the effective potential, constructed in terms of
a gauge invariant order parameter. We compare the results with another
investigation, obtained within a standard route of calculating the effective
potential.Comment: 10 pages. Revtex. To appear in Phys. Rev.
