Tree Quantum Field Theory
R. Gurau, J. Magnen, V. Rivasseau
We propose a new formalism for quantum field theory which is neither based on functional integrals, nor on Feynman graphs, but on marked trees. This formalism is constructive, i.e.…
A translation-invariant renormalizable non-commutative scalar model
R. Gurau, J. Magnen, V. Rivasseau +1
In this paper we propose a translation-invariant scalar model on the Moyal space. We prove that this model does not suffer from the UV/IR mixing and we establish its renormalizabil…
Constructive field theory without tears
J. Magnen, V. Rivasseau
We propose to treat the Euclidean theory constructively in a simpler way. Our method, based on a new kind of "loop vertex expansion", no longer requires the painful intermedi…
Vanishing of Beta Function of Non Commutative Theory to all orders
M. Disertori, R. Gurau, J. Magnen +1
The simplest non commutative renormalizable field theory, the model on four dimensional Moyal space with harmonic potential is asymptotically safe up to three loops, as shown…
Interacting Fermi liquid in three dimensions at finite temperature: Part I: Convergent Contributions
M. Disertori, J. Magnen, V. Rivasseau
In this paper we complete the first step, namely the uniform bound on completely convergent contributions, towards proving that a three dimensional interacting system of Fermions i…
Bosonic Monocluster Expansion
A. Abdesselam, J. Magnen, V. Rivasseau
We compute connected Green's functions of a Bosonic field theory with cutoffs by means of a ``minimal'' expansion which in a single move, interpolating a generalized propagator, pe…
