QED plasma in a background of static gravitational fields
F. T. Brandt, J. Frenkel, J. B. Siqueira
We obtain the effective Lagrangian of static gravitational fields interacting with a QED plasma at high temperature. Using the equivalence between the static hard thermal loops and…
Hard thermal loops in static background fields
F. T. Brandt, J. Frenkel, J. B. Siqueira
We discuss the high temperature behavior of retarded thermal loops in static external fields. We employ an analytic continuation of the imaginary time formalism and use a spectral…
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…
Resummation of infrared divergences in the free-energy of spin-two fields
F. T. Brandt, J. Frenkel, D. G. C. McKeon +1
We derive a closed form expression for the sum of all the infrared divergent contributions to the free-energy of a gas of gravitons. An important ingredient of our calculation is t…
