Renormalized thermodynamics from the 2PI effective action
We calculate the pressure as well as other thermodynamic quantities for a scalar one-component field theory from a three-loop 2PI effective action numerically without further approximations. We present a detailed comparison with the two-loop approximation. One observes a strongly improved convergence behavior as compared to perturbative approaches. The renormalization employed in this work exte...
متن کاملEffective Action and Renormalization Group Flow of Anisotropic Superconductors
We calculate the effective action of a superconductor, without assuming that either the electron-electron potential or the Fermi surface obey rotational invariance. This approach leads to the same gap equation and equilibrium free energy as more conventional methods. The results are used to obtain the Gell-Mann Low renormalization group equations for the electron-electron potential. Research su...
متن کاملDifferential Renormalization, the Action Principle and Renormalization Group Calculations
General prescriptions of differential renormalization are presented. It is shown that renormalization group functions are straightforwardly expressed through some constants that naturally arise within this approach. The status of the action principle in the framework of differential renormalization is discussed.
متن کاملPhenomenological Renormalization Group Methods
Some renormalization group approaches have been proposed during the last few years which are close in spirit to the Nightingale phenomenological procedure. In essence, by exploiting the finite size scaling hypothesis, the approximate critical behavior of the model on infinite lattice is obtained through the exact computation of some thermal quantities of the model on finite clusters. In this wo...
متن کاملGauge Dependence of Effective Action and Renormalization Group Functions in Effective Gauge Theories
The Caswell-Wilczek analysis on the gauge dependence of the effective action and the renormalization group functions in Yang-Mills theories is generalized to generic, possibly power counting non renormalizable gauge theories. It is shown that the physical coupling constants of the classical theory can be redefined by gauge parameter dependent contributions of higher orders in “hbar” in such a w...
