Nonanalyticity of the induced Carroll-Field-Jackiw term at finite temperature | | J. F. Assuncao

28 Sep 2016 | | Abstract: | In this paper, we discuss the behavior of the Carroll-Field-Jackiw (CFJ)
coefficient $k^{mu}$ arising due to integration over massive fermions, and the
modification suffered by its topological structure in the finite temperature
case. Our study is based on the imaginary time formalism and summation over the
Matsubara frequencies. We demonstrate that the self-energy of photon is
non-analytic for the small $k^{mu}$ limit, i.e., the static limit $(k_0=0,vec
k
ightarrow 0)$ and the long wavelength limit $(k_0
ightarrow 0,vec k= 0)$
do not commute, while the tensorial structure of the CFJ term holds in both
limits. | | Source: | arXiv, 1609.9120 | | Services: | Forum | Review | PDF | Favorites | |
