The gravitational polarization tensor of thermal theory
H. Nachbagauer, A. K. Rebhan, D. J. Schwarz
The low-momentum structure of the gravitational polarization tensor of an ultrarelativistic plasma of scalar particles with interactions is evaluated in a two-loop calculati…

Thermal Green's Functions from Quantum Mechanical Path Integrals II: Inclusion of Fermions
D G C McKeon, a K Rebhan
In a previous paper we have shown how, for bosonic fields, the generating functional in both relativistic quantum field theory and thermal field theory can be evaluated by use of a…

Thermal Green's Functions from Quantum Mechanical Path Integrals
D. G. C. McKeon, A. Rebhan
In this paper it is shown how the generating functional for Green's functions in relativistic quantum field theory and in thermal field theory can be evaluated in terms of a standa…
