Holographic renormalization [PDF]

open access: yesNuclear Physics B, 2002
We systematically develop the procedure of holographic renormalization for RG flows dual to asymptotically AdS domain walls. All divergences of the on-shell bulk action can be cancelled by adding covariant local boundary counterterms determined by the near-boundary behavior of bulk fields.

Renormalized quarkonium [PDF]

open access: yesPhysical Review D, 2012
We extend our previous study of the vector charmonium states within a renormalization approach with boundary conditions to the full spectrum of charmonium and bottomonium. On the light of the predicted spectrum we comply to assignments suggested in the literature. A comparison with the regularized quark model is also included.

On the renormalization of Hamiltonians [PDF]

open access: yesAIP Conference Proceedings, 1999
We introduce a novel method for the renormalization of the Hamiltonian operator in Quantum Field Theory in the spirit of the Wilson renormalization group. By a series of unitary transformations that successively decouples the high-frequency degrees of freedom and partially diagonalizes the high-energy part, we obtain the effective Hamiltonian for the ...

Multigrid renormalization [PDF]

open access: yesJournal of Computational Physics, 2018
We combine the multigrid (MG) method with state-of-the-art concepts from the variational formulation of the numerical renormalization group. The resulting MG renormalization (MGR) method is a natural generalization of the MG method for solving partial differential equations.

Renormalization of Hamiltonians [PDF]

open access: yesPhysical Review D, 1993
A matrix model of an asymptotically free theory with a bound state is solved using a perturbative similarity renormalization group for hamiltonians. An effective hamiltonian with a small width, calculated including the first three terms in the perturbative expansion, is projected on a small set of effective basis states. The resulting small hamiltonian

Regularization in quantum field theories

open access: yesVojnotehnički Glasnik, 2022
Introduction/purpose: The principal techniques of regularization schemes and their validity for gauge field theories are discussed. Methods: Schemes of dimensional regularization, Pauli–Villars and lattice regularization are discussed.
