Multi-frequency averaging and uniform accuracy towards numerical approximations for a Bloch model
Brigitte Bidégaray-Fesquet, Clément Jourdana, Léopold Trémant
We are interested in numerically solving a transitional model derived from the Bloch model. The Bloch equation describes the time evolution of the density matrix of a quantum syste…
Static ferromagnetic materials: from the microscopic to the mesoscopic scale
Brigitte Bidégaray-Fesquet, Quentin Jouet, Stéphane Labbé
Thanks to averaging processes and Gamma-convergence techniques, we are able to link a microscopic description of ferromagnetic materials based on spin lattices and their mesoscopic…
On the propagation of an optical wave in a photorefractive medium
Brigitte Bidégaray-Fesquet, Jean-Claude Saut
The aim of this paper is first to review the derivation of a model describing the propagation of an optical wave in a photorefractive medium and to present various mathematical res…
