Development of a metrological measurement of the Casimir-Polder potential through the diffraction of metastable argon atoms by material nanogratings under normal or oblique incidence

I am pleased to announce that my PhD defense will take place on Thursday, January 9th at 2PM in the Fermat amphitheater.

My thesis focuses on the development of a metrological measurement of the Casimir-Polder potential through the diffraction of metastable argon atoms by material nanogratings under normal or oblique incidence.

I will present the experimental setup as well as the theoretical models used to measure the Casimir-Polder potential. I will then discuss an analysis of the measurements we have performed and share preliminary results on a new technique for measuring the Casimir-Polder potential involving the inclination of the nanograting.
