On the Running Gauge Coupling Constant in the Exact Renormalization Group
Jun-Ichi Sumi
In this paper, we investigate the beta-function of the gauge coupling constant () of the gauged four-fermi theory in the Exact Renormalization Group (ERG) framework. It seems th…
Scheme Dependence of the Wilsonian Effective Action and Sharp Cutoff Limit of the Flow Equation
Jun-Ichi Sumi, Wataru Souma, Ken-Ichi Aoki +2
The cutoff scheme dependence in the several formulations of the Exact Renormalization Group (ERG) is investigated. It is shown that the cutoff scheme dependence of the Wilsonian ef…

Hiroaki Kodama, Jun-Ichi Sumi
The chiral phase structure of the Nambu-Jona-Lasinio/Gross-Neveu model at finite temperature T and finite chemical potential μis investigated using (Wilsonian) Non-Perturbative Ren…
Analysis of the Wilsonian Effective Potentials in Dynamical Chiral Symmetry Breaking
Ken-Ichi Aoki, Keiichi Morikawa, Jun-Ichi Sumi +2
The non-perturbative renormalization group equation for the Wilsonian effective potential is given in a certain simple approximation scheme in order to study chiral symmetry breaki…
Wilson Renormalization Group Equations for the Critical Dynamics of Chiral Symmetry
Ken-Ichi Aoki, Keiichi Morikawa, Jun-Ichi Sumi +2
The critical dynamics of the chiral symmetry breaking induced by gauge interaction is examined in the Wilson renormalization group framework in comparison with the Schwinger-Dyson…
Rapidly Converging Truncation Scheme of the Exact Renormalization Group
Ken-Ichi Aoki, Keiichi Morikawa, Wataru Souma +2
The truncation scheme dependence of the exact renormalization group equations is investigated for scalar field theories in three dimensions. The exponents are numerically estimated…
