Random Matrices and the Anderson Model
M. Disertori, V. Rivasseau
In recent years,constructive field techniques and the method of renormalization group around extended singularities have been applied to the weak coupling regime of the Anderson Mo…
Supersymmetric Analysis of a Simplified Two Dimensional Anderson Model at Small Disorder
J. Bellissard, J. Magnen, V. Rivasseau
This work proposes a very simple random matrix model, the Flip Matrix Model, liable to approximate the behavior of a two dimensional electron in a weak random potential. Its constr…
The two dimensional Hubbard Model at half-filling: I. Convergent Contributions
Vincent Rivasseau
We prove analyticity theorems in the coupling constant for the Hubbard model at half-filling. The model in a single renormalization group slice of index is proved to be analyti…
Constructive Renormalization Theory
V. Rivasseau
These notes are the second part of a common course on Renormalization Theory given with Professor P. da Veiga at X Jorge Andre Swieca Summer School, Aguas de Lindoia, Brazil, Febru…
Explicit Fermionic Tree Expansions
A. Abdesselam, V. Rivasseau
We express connected Fermionic Green's functions in terms of completely explicit tree formulas. In contrast with the ordinary formulation in terms of Feynman graphs these formulas…
