  • We use a generalised real-time path formalism with properly regularised propagators based on Le Bellac and Mabilat \cite{belmab} and calculate the effective potential and the higher order derivative terms of the effective action in the case of real scalar fields at finite temperature. We consider time-dependent fields in thermal equilibrium and concentrate on the quadratic part of the expanded effective action which has been associated with problems of non-analyticity at the zero limits of the… CONTINUE READING
