TLDR
In this paper, the authors point out that the claims made in the paper ''Nonthermalizability of a Quantum Field Theory'' (hepth/9802008) by C. R. Hagen are irrelevant to our recent results concerning large gauge invariance of the effective action in thermal QED.Abstract:

Finite Temperature Chern-Simons Coefficient
TL;DR: In this article, the exact finite temperature effective action in a (0+1)-dimensional field theory containing a topological Chern-Simons term was computed, which has many features in common with 2+1-dimensional Chern-simons theories.
Journal ArticleDOI
Gauge Invariance, Finite Temperature, and Parity Anomaly in D = 3
TL;DR: In this paper, it was shown that the perturbative expansion is not invariant to large transformations and hence their Ward identities are not perturbation order preserving, and that large transformations can be made invariant under small and large transformations at any temperature.
Journal ArticleDOI
Induced parity breaking term at finite temperature
TL;DR: In this paper, the exact induced parity-breaking part of the effective action for massive fermions at finite temperature was computed by calculating the fermion determinant in a particular background.

Gauge Invariance and Effective Actions in D=3 at Finite Temperature
TL;DR: For background gauge field configurations reducible to the form Amu = (A3, A(x)) where A3 is a constant, this paper provided an elementary derivation of the recently obtained result for the exact induced Chern-Simons (CS) effective action in QED3 at finite temperature.

Reducing the Chern–Simons term by a symmetry
R. Jackiw,So-Young Pi +1 more
TL;DR: In this article, a 3D Chern-Simons term is reduced by radial symmetry to a 1-dimensional quantum model, which has been used in an analysis of finite-temperature Chern-simons theory.
