Anderson-Higgs amplitude mode in Josephson junctions
Pierre Vallet, Jérôme Cayssol
The Anderson-Higgs mode in a superconductor corresponds to a collective and coherent oscillation of the order parameter amplitude. We propose to detect this mode in a tunnel Joseph…

Thermogravimetric study of the non-stoichiometric wüstite FeOx. Pseudo phases w i and w' i . New T-P-X equilibrium phase diagram
Pierre Vallet, Claude Carel
A statistical numerical analysis of thermogravimetric measurements (temperature, mass variation, oxygen pressure) leads to a new equilibrium phase diagram T-P-X of the iron monoxid…

About a first order transformation of magnetite at 1 160 °C
Claude Carel, Pierre Vallet
In the literature on the w{ü}stite/magnetite transformation, there are two distinct values of the enthalpy and entropy terms of the equilibrium between these two oxides. The formal…
