Resummation methods at finite temperature: The tadpole way.
We examine several resummation methods for computing higher order corrections to the finite temperature effective potential, in the context of a scalar φ4 theory. We show by explicit calculation to four loops that dressing the propagator, not the vertex, of the one-loop tadpole correctly counts “daisy” and “super-daisy” diagrams. Work supported in part by the U.S. Dept. of Energy under Contract...
متن کاملOn daisy and superdaisy resummation of the effective potential at finite temperature
We describe in detail, in the context of the simplest scalar φ4 theory, the prescription for resummation of daisy and superdaisy diagrams in the effective potential using the solution of the gap equations in the infrared limit. We find that the latter procedure is consistent provided we neglect logarithmic terms from the finite-temperature self energies and from the integration of overlapping m...
متن کاملDynamical Renormalization Group Resummation of Finite Temperature Infrared Divergences
We introduce the method of dynamical renormalization group to study relaxation and damping out of equilibrium directly in real time and applied it to the study of infrared divergences in scalar QED. This method allows a consistent resummation of infrared effects associated with the exchange of quasistatic transverse photons and leads to anomalous logarithmic relaxation of the form e−αTt ln[t/t0...
متن کاملRenormalization and resummation in finite temperature field theories
Resummation, ie. reorganization of perturbative series, can result in an inconsistent perturbation theory, unless the counterterms are reorganized in an appropriate way. In this paper two methods are presented for resummation of counterterms: one is a direct method where the necessary counterterms are constructed order by order; the other is a general one, based on renormalization group argumen...
متن کاملQuantum Monte Carlo Methods for Nuclei at Finite Temperature
We discuss finite temperature quantum Monte Carlo methods in the framework of the interacting nuclear shell model. The methods are based on a representation of the imaginary-time many-body propagator as a superposition of one-body propagators describing non-interacting fermions moving in fluctuating auxiliary fields. Fermionic Monte Carlo calculations have been limited by a “sign” problem. A pr...
