Large N and the Renormalization Group Marco
In the large N limit, we show that the Local Potential Approximation to the flow equation for the Legendre effective action, is in effect no longer an approximation, but exact – in a sense, and under conditions, that we determine precisely. We explain why the same is not true for the Polchinski or Wilson flow equations and, by deriving an exact relation between the Polchinski and Legendre effec...
متن کاملNon-analyticity in the large N renormalization group
The flow of the action induced by changing N is computed in large N matrix models. It is shown that the change in the action is non-analytic. This non-analyticity appears at the origin of the space of matrices if the action is even.
متن کاملRenormalization Group Functions of Qcd in Large N F *
We review the application of the critical point large N f self-consistency method to QCD. In particular we derive the O(1/N f) d-dimensional critical exponents whose ǫ-expansion determines the perturbative coefficients in MS of the field dimensions, β-function and various twist-2 operators which occur in the operator product expansion of deep inelastic scattering.
متن کاملFunctional renormalization group at large N for disordered systems.
We introduce a method, based on an exact calculation of the effective action at large N, to bridge the gap between mean-field theory and renormalization in complex systems. We apply it to a d-dimensional manifold in a random potential for large embedding space dimension N. This yields a functional renormalization group equation valid for any d, which contains both the O(epsilon=4-d) results of ...
متن کاملLarge N Renormalization Group for Random Matrix Models
We report on our recent studies of the large N renormalization group (RG) method which clariies phase structure of random matrix models. We derive an exact RG equation which enables us to obtain the exact locations of xed points and their scaling exponents. The classiication of phases is given by this analysis. A linear approximation visualizes the RG ow of crossover phenomena including several...
