Thermodynamics of the PHI4 Theory in Tadpole Approximation

Peshier, A.; Kämpfer, B.; Pavlenko, O. P.; Soff, G.

Relying on the Luttinger-Ward theorem we derive a thermodynamically selfconsistent and scale independent approximation of the thermodynamic potential for the scalar Φ4 theory in the tadpole approximation. The resulting thermodynamic potential as a function of the temperature is similar to the one of the recently proposed screened perturbation theory.
