On The Finite Temperature Chern-Simons Coefficient
We compute the exact finite temperature effective action in a 0+1dimensional field theory containing a topological Chern-Simons term, which has many features in common with 2+1-dimensional Chern-Simons theories. This exact result explains the origin and meaning of puzzling temperature dependent coefficients found in various naive perturbative computations in the higher dimensional models. There...
متن کاملInduced Chern-Simons term in lattice QCD at finite temperature
The general conditions for the Chern-Simons action to be induced as a nonuniversal contribution of fermionic determinant are formulated in the finite temperature lattice QCD. The dependence of the corresponding action coefficient on nonuniversal parameters (chemical potentials, vacuum features, etc. ) is explored. Special attention is paid to the role of A0-condensate if it is available in this...
متن کاملOn the Chern-Simons Topological Term at Finite Temperature
The parity-violating topological term in the effective action for 2+1 massive fermions is computed at finite temperature in the presence of a constant background field strength tensor. Gauge invariance of the finite-temperature effective action is also discussed. A remarkable property of three dimensional gauge theories coupled to matter is the dynamical generation of the Chern-Simons (CS) topo...
متن کاملThe induced Chern–Simons term at finite temperature
It is argued that the derivative expansion is a suitable method to deal with finite temperature field theory, if it is restricted to spatial derivatives only. Using this method, a simple and direct calculation is presented for the radiatively induced Chern– Simons-like piece of the effective action of (2+ 1)-dimensional fermions at finite temperature coupled to external gauge fields. The gauge ...
متن کاملThe Chern-Simons Coefficient in Supersymmetric Non-Abelian Chern-Simons Higgs Theories
By taking into account the effect of the would be Chern-Simons term, we calculate the quantum correction to the Chern-Simons coefficient in supersymmetric Chern-Simons Higgs theories with matter fields in the fundamental representation of SU(n). Because of supersymmetry, the corrections in the symmetric and Higgs phases are identical. In particular, the correction is vanishing for N = 3 supersy...
