Generation of Electric Current by Magnetic Field at the Boundary: Quantum Scale Anomaly Versus Semiclassical Meissner Current Outside of the Conformal Limit

open access: yesAdvanced Physics Research, EarlyView., 2023
The paper discusses the role of scale anomaly in generating edge electric currents via the scale magnetic effect in scalar electrodynamics. Although the boundary electric current is much weaker than the Meissner current induced in superconducting materials, the scale anomaly can enhance conductivity near the boundary of the material.

Local renormalization group functions from quantum renormalization group and holographic bulk locality [PDF]

open access: yes, 2015
The bulk locality in the constructive holographic renormalization group requires miraculous cancellations among various local renormalization group functions. The cancellation is not only from the properties of the spectrum but from more detailed aspects

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

QUELLE CONCEPTION DE LA RENORMALISATION DANS LE MÉTIER D’ENSEIGNANT ?

open access: yesQuestions Vives, 2023
This article explores the tensions between prescribed norms and teachers’ real activity through the analysis of a training program designed to support their adoption of the Narramus method, recently introduced in Geneva’s primary schools.

Stochastic Electrodynamics: Renormalized Noise in the Hydrogen Ground-State Problem

open access: yesFrontiers in Physics, 2020
The hydrogen ground-state problem is a touchstone for the theory of Stochastic Electrodynamics. Recently, we have shown numerically and theoretically that the H-atom self-ionizes after a characteristic time.

Renormalization aspects of N=1 Super Yang-Mills theory in the Wess-Zumino gauge [PDF]

open access: yes, 2014
The renormalization of N=1 Super Yang-Mills theory is analysed in the Wess-Zumino gauge, employing the Landau condition. An all orders proof of the renormalizability of the theory is given by means of the Algebraic Renormalization procedure.

Renormalization group and nonequilibrium action in stochastic field theory [PDF]

open access: yes, 2002
We investigate the renormalization group approach to nonequilibrium field theory. We show that it is possible to derive nontrivial renormalization group flow from iterative coarse graining of a closed-time-path action.
