They express the renormalization group invariance of quantum mechanics. The present approach for the renormalization scheme relies on a subtracted T-matrix equation.27-34engrenormalizationrenormalization groupHamiltonian approachscattering theoryArtigo10.1556/APH.16.2002.1-4.4WOS:000179714300004Acesso restrito
