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…

Non-Perturbative Renormalization Group and Quantum Tunnelling
Ken-Ichi Aoki, Atsushi Horikoshi, Masaki Taniguchi +1
The non-perturbative renormalization group (NPRG) is applied to analysis of tunnelling in quantum mechanics. The vacuum energy and the energy gap of anharmonic oscillators are eval…
