Collective Excitations in Thermal QED_{3+1}: Survival of the Fittest
I. V. Tyutin, Vadim Zeitlin
The spectrum of collective fermionic excitations in a finite temperature QED_{3+1} is studied in different regimes. It is shown that within the standard perturbation approach the o…

Comment on "Dynamical Chern-Simons term generation at finite density" and "Chern-Simons term at finite density"
Vadim Zeitlin
We comment on the calculation of the Chern-Simons coefficient in (2+1)-dimensional gauge theories at finite chemical potential made by A.N.Sissakian, O.Yu.Shevchenko and S.B.Solgan…
