Florence Levy-Bertrand


I am a CNRS experimentalist physicist in condensed matter working at the Néel Institute Laboratory, Grenoble, France. I am particularly involved in the study of superconductivity. Lately, I have been working on sub-THz and sub-Kelvin optical spectroscopy measurements of disordered superconductors (granular aluminum and amorphous indium oxide thin films). A key issue in this field is to detect and explain possible collective modes below the superconducting gap.
