چکیده
A new version of the cluster expansion is proposed without breaking translation and rotation invariance. As an application this technique, we construct connected Schwinger functions regularized $$\phi ^4$$ theory in a continuous way.

Renormalizable 1/Nf Expansion for Field Theories in Extra Dimensions
We demonstrate how one can construct renormalizable perturbative expansion in formally nonrenormalizable higher dimensional field theories. It is based on 1/Nf -expansion and results in a logarithmically divergent perturbation theory in arbitrary high space-time dimension. First, we consider a simple example of N -component scalar filed theory and then extend this approach to Abelian and nonAbe...
متن کاملLogarithmic Conformal Field Theories with Continuous Weights
We study the logarithmic conformal field theories in which conformal weights are continuous subset of real numbers. A general relation between the correlators consisting of logarithmic fields and those consisting of ordinary conformal fields is investigated. As an example the correlators of the Coulomb-gas model are explicitly studied.
متن کاملCluster dynamical mean-field theories: Causality and classical limit
Cluster dynamical mean field theories are analyzed in terms of their semiclassical limit and their causality properties, and a translation invariant formulation of the cellular dynamical mean-field theory, periodized cluster dynamical mean-field theory ~PCDMFT!, is presented. The semiclassical limit of the cluster methods is analyzed by applying them to the Falikov-Kimball model in the limit of...
متن کاملAn Explicit Large Versus Small Field Multiscale Cluster Expansion
We introduce a new type of cluster expansion which generalizes a previous formula of Brydges and Kennedy. The method is especially suited for performing a phase-space multiscale expansion in a just renormalizable theory, and allows the writing of explicit non-perturbative formulas for the Schwinger functions. The procedure is quite model independent, but for simplicity we chose the infrared φ 4...
متن کاملRenormalizable Expansion for Nonrenormalizable Theories: I. Scalar Higher Dimensional Theories
We demonstrate how one can construct renormalizable perturbative expansion in formally nonrenormalizable higher dimensional scalar theories. It is based on 1/N -expansion and results in a logarithmically divergent perturbation theory in arbitrary high odd space-time dimension. The resulting effective coupling is dimensionless and is running in accordance with the usual RG equations. The corresp...
