Exact Renormalization Group : A New Method for Blocking the Action . Jean - Michel Caillol LPT - CNRS ( UMR 8627 ) Bât
We consider the exact renormalization group for a non-canonical scalar field theory in which the field is coupled to the external source in a special non linear way. The Wilsonian action and the average effective action are then simply related by a Legendre transformation up to a trivial quadratic form. An exact mapping between canonical and non-canonical theories is obtained as well as the rel...

This is a very brief introduction to Wilson’s Renormalization Group with emphasis on mathematical developments.
متن کاملTime-Dependent Real-Space Renormalization Group Method
In this paper, using the tight-binding model, we extend the real-space renormalization group method to time-dependent Hamiltonians. We drive the time-dependent recursion relations for the renormalized tight-binding Hamiltonian by decimating selective sites of lattice iteratively. The formalism is then used for the calculation of the local density of electronic states for a one dimensional quant...
متن کاملA NUMERICAL RENORMALIZATION GROUP APPROACH FOR AN ELECTRON-PHONON INTERACTION
A finite chain calculation in terms of Hubbard X-operators is explored by setting up a vibronic Harniltonian. The model conveniently transformed into a form so that in the case of strong coupling a numerical renormalization group approach is applicable. To test the technique, a one particle Green function is calculated for the model Harniltonian
متن کاملExact Renormalization Group with Fermions
The set of ideas enclosed in the Renormalization Group (RG, hereafter) has led to a variety of developments in many fields, as this Conference has made apparent. From a particle theorist point of view they englobe a bunch of ideas form which we may understand what a quantum field theory is. Moreover, it provides a framework for nonperturbative calculations. In recent years, there has been an in...
