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. ...
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 ...
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 ...
Recursive renormalization of the singlet one-pion-exchange plus point-like interactions

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 ...
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 ...
Thermoelectric effects in quantum dots
(2009-10-15)
We report a numerical renormalization-group study of the thermoelectric effect in the single-electron transistor (SET) and side-coupled geometries. As expected, the computed thermal conductance and thermopower curves show ...
Effective potential in curved space and cut-off regularizations
(Elsevier B.V., 2011-11-11)
We consider derivation of the effective potential for a scalar field in curved space-time within the physical regularization scheme, using two sorts of covariant cut-off regularizations. The first one is based on the local ...
Holographic renormalization flows, entanglement entropy and the sum rule
(Springer, 2016-03-07)
We calculate the two-point function of the trace of the stress tensor in holographic renormalization group flows between pairs of conformal field theories. We show that the term proportional to the momentum squared in this ...
Non-Fermi-liquid superconductivity: Eliashberg approach versus the renormalization group
(American Physical Society, 2017-04)
We address the problem of superconductivity for non-Fermi liquids using two commonly adopted, yet apparently distinct, methods: (1) the renormalization group (RG) and (2) Eliashberg theory. The extent to which both methods ...
