Renormalization in few-body nuclear physics
(Akademiai Kiado, 2002-01-01)
Renormalized fixed-point Hamiltonians are formulated for systems described by interactions that originally contain point-like singularities (as the Dirac-delta and/or its derivatives). They express the renormalization group ...
Renormalization group invariance of quantum mechanics
(Elsevier B.V., 2000-05-18)
We propose a framework to renormalize the nonrelativistic quantum mechanics with arbitrary singular interactions. The scattering equation is written to have one or more subtraction in the kernel at a given energy scale. ...
Recursive renormalization of the singlet one-pion-exchange plus point-like interactions
(Elsevier B.V., 2005-08-11)
The subtracted kernel approach is shown to be a powerful method to be implemented recursively in scattering equations with regular plus point-like interactions. The advantages of the method allows one to recursively ...
Renormalization of the one-pion-exchange interaction
(1999-07-05)
A renormalization scheme for the nucleon-nucleon (NN) interaction based on a subtracted T-matrix equation is proposed and applied to the one-pion-exchange potential supplemented by contact interactions. The singlet and ...
Recursive renormalization of the singlet one-pion-exchange plus point-like interactions

Renormalization and Short Distance Singular Structure
(Springer/plenum Publishers, 2001-12)
The relation between renormalization and short distance singular divergencies in quantum field theory is studied. As a consequence a finite theory is presented. It is shown that these divergencies originate from the ...
Recursive computation of matrix elements in the numerical renormalization group
(Elsevier BVAmsterdam, 2014-04)
The numerical renormalization group is an efficient method to diagonalize model Hamiltonians describing correlated orbitals coupled to conduction states. While only the resulting eigenvalues are needed to calculate the ...
Exact renormalization of massless QED(2)
(World Scientific Publ Co Pte Ltd, 2002-12-10)
We perform the exact renormalization of two-dimensional massless gauge theories. Using these exact results we discuss the cluster property and confinement in both the anomalous and chiral Schwinger models.
Renormalization of singular potentials and power counting
(Academic Press Inc. Elsevier B.V., 2008-06-01)
We use a toy model to illustrate how to build effective theories for singular potentials. We consider a central attractive 1/r(2) potential perturbed by a 1/r(4) correction. The power-counting rule, an important ingredient ...
Holographic renormalization in teleparallel gravity
(Springer, 2017-01-24)
We consider the problem of IR divergences of the action in the covariant formulation of teleparallel gravity in asymptotically Minkowski spacetimes. We show that divergences are caused by inertial effects and can be removed ...
