Ginzton Laboratory, Stanford University, United States) candidat CNRS section 3 Light-Matter Interactions in Semiconductors: From Condensates of Exciton-Polaritons to Scalable Platforms for Quantum Information Processing (Physique de l'exciton, du photon et du spin) Light-matter interactions lie at the heart of a very broad range of fundamental physics and applications. At a single particle level, such interactions enable all-optical quantum control of qubits which is of great interest for quantum information. At a more macroscopic level, these interactions are a key to collective phenomena such as condensation of exciton-polaritons in microcavities. In this talk I will present my previous and current research which is unified under the broad field of light-matter interactions in semiconductors. In particular, I will briefly introduce polariton condensates along with the typical experimental methods used for their study and will cover a few exciting experiments ranging from the observation of pinned singly-charged vortices to the demonstration of a polaritonic Josephson junction. Moving from such collective quasi-particle phenomena to the investigation of more discreet quantum emitter systems, I will then address experimental efforts on the coherent control of scalable quantum emitter platforms. More specifically, I will present recent work on site-controlled quantum dots and silicon vacancies in diamond, and will conclude with an overview of my vision for future research. --------- Pour plus d'informations, merci de contacter Vladimirova M. |
