An ab initio study of magneto-electric coupling of
J. Varignon, S. Petit, A. Gellé +1
The present paper proposes the direct calculation of the microscopic contributions to the magneto-electric coupling, using ab initio methods. The electrostrictive and the Dzyaloshi…
Entropy driven atomic motion in laser-excited bismuth
Y. Giret, A. Gellé, B. Arnaud
We introduce a thermodynamical model based on the two-temperature approach in order to fully understand the dynamics of the coherent A phonon in laser-excited bismuth. Using…
Fast calculation of the electrostatic potential in ionic crystals by direct summation method
Alain Gellé, Marie-Bernadette Lepetit
An efficient real space method is derived for the evaluation of the Madelung's potential of ionic crystals. The proposed method is an extension of the Evjen's method. It takes adva…

Electronic structure of the incommensurate compound
Alain Gelle, Marie-Bernadette Lepetit
We extracted, from strongly-correlated ab-initio calculations, a complete model for the chain subsystem of the incommensurate compound. A second ne…
Environment effects on effective magnetic exchange integrals and local spectroscopy of extended strongly correlated systems
Marie-Bernadette Lepetit, Nicolas Suaud, Alain Gelle +1
The present work analyzes the importance of the different components of the environment effects on the local spectroscopy of extended strongly correlated systems. It has been found…
Influence of the incommensurability in family compounds
Alain Gellé, Marie-Bernadette Lepetit
The present paper studies the influence of the structural modulation on the low energy physics of the oxides, using ab-initio determination of the on-s…
