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 ...
Langevin simulation of scalar fields: Additive and multiplicative noises and lattice renormalization
(Elsevier B.V., 2012-08-15)
We consider the Langevin lattice dynamics for a spontaneously broken 44 scalar field theory where both additive and multiplicative noise terms are incorporated. The lattice renormalization for the corresponding stochastic ...

Renormalization of Generalized Quantum Electrodynamics
(2015-01-01)
In the present work we shall study the renormalizability of Generalized Quantum Electrodynamics (GQED4). The on-shell renormalization scheme is reviewed and applied to the theory and we calculate the explicit expressions ...
Hyperbolicity of renormalization for dissipative gap mappings
(2021-01-01)
A gap mapping is a discontinuous interval mapping with two strictly increasing branches that have a gap between their ranges. They are one-dimensional dynamical systems, which arise in the study of certain higher dimensional ...

Renyi relative entropies and renormalization group flows
(Springer, 2018-09)
Quantum Renyi relative entropies provide a one-parameter family of distances between density matrices, which generalizes the relative entropy and the fidelity. We study these measures for renormalization group flows in ...
Adiabatic renormalization in theories with modified dispersion relations
(IOP Publishing, 2007-12)
We generalize the adiabatic renormalization to theories with dispersion relations modified at energies higher than a new scale MC. We obtain explicit expressions for the mean value of the stress tensor in the adiabatic ...
