MESURER OPTIQUEMENT LE MAGNETISME SOUS TRES HAUTE PRESSION GRACE AUX DEFAUTS DU DIAMANT
J.-F. ROCH
LUMIN, France
La cellule à enclumes de diamant est un dispositif de laboratoire créant des pressions où apparaissent de nouveaux états quantiques de la matière. L'intégration dans l’enclume de diamant d’atomes artificiels optiquement actifs, agissant comme capteur in situ, permet d’explorer des états supraconducteurs à très haute température critique.

SPIN MECHANICS WITH LEVITATING PARTICLES
G. HÉTET
LPENS, France
I will present our experimental platform composed of a levitating diamond particle containing electronic spins from Nitrogen-Vacancy (NV) centers and our recent observations of spin-dependent torque and dynamical back-action induced cooling of the diamond libration.

REFLECTANCE FROM SINGLE EXCITONS: CONTEXT AND PROSPECTS
J. KASPRZAK
CNRS, France
Reflectivity is one of the most straightforward and insightful approaches of optical spectroscopy. In this talk, I will highlight how to measure reflectance from a single exciton and why. I hope to showe that such experiment yields pertinent results and prospects in the field of coherence of condensed matter and optical quantum engineering.
