A way to get a well-defined derivative expansion of real-time thermal effective actions
Maria Asprouli, Victor Galan-Gonzalez
We compute the quadratic part of the thermal effective action for real scalar fields which are initially in thermal equilibrium and vary slowly in time using a generalised real-tim…

Derivative expansions of real-time thermal effective actions
Maria Asprouli, Victor Galan-Gonzalez
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 highe…
