Nonanalyticity of the free energy in thermal field theory
F. T. Brandt, J. Frenkel, J. B. Siqueira
We study, in a d-dimensional space-time, the nonanalyticity of the thermal free energy in the scalar phi^4 theory as well as in QED. We find that the infrared divergent contributio…

High temperature limit in static backgrounds
F. T. Brandt, J. B. Siqueira
We prove that the hard thermal loop contribution to static thermal amplitudes can be obtained by setting all the external four-momenta to zero before performing the Matsubara sums…

Thermal Effective Lagrangian of Static Gravitational Fields
F T Brandt, J B Siqueira
We compute the effective Lagrangian of static gravitational fields interacting with thermal fields. Our approach employs the usual imaginary time formalism as well as the equivalen…
