Renormalization group flow equations with full momentum dependence (1110.3413v1)
Published 15 Oct 2011 in cond-mat.stat-mech, hep-th, and nucl-th
Abstract: After a short elementary introduction to the exact renormalization group for the effective action, I discuss a particular truncation of the hierarchy of flow equations that allows for the determination of the full momentum of the $n$-point functions. Applications are then briefly presented, to critical O(N) models, to Bose-Einstein condensation and to finite temperature field theory.
