Constructing a weakly-interacting fixed point of the Fermionic Polchinski equation
arXiv:2401.04462 · doi:10.1063/5.0203607
Abstract
I rigorously prove the existence of a nontrivial fixed point of a family of continuous renormalization group flows corresponding to certain weakly interacting Fermionic quantum field theories with a parameter in the propagator allowing the scaling dimension to be tuned in a manner analogous to dimensional regularization.
