Dylan CATTIAUX received the 2022 Academic Thesis Prize for her research work among PhDs graduating in 2021.
Thesis Title: Ultra-low temperatures microwave optomechanics for quantum sensing
In order to perform such experiments at the frontier of modern physics, we created a unique micro-wave/micro-Kelvin opto-mechanical platform. We demonstrate for the first time the passive cooling of a 15MHz aluminium drumhead mechanical device down to 500 micro-K, reaching a population for the fundamental mode of 0.3 quanta on average; all higher modes being empty to a very high probability. Using microwave opto-mechanics as a non-invasive detector, we report on the in-equilibrium thermal properties of this lowest frequency mode, challenging theory in an unprecedented experimental area.
Dylan Cattiaux died tragically in the mountains after his defense at the age of 26. He had already been awarded for his thesis by the MecaQ research group, which wished to name the "Optomechanics and Nanomechanics Thesis Prize" after the first prize-winning doctor. From now on, it will be called the "Dylan Cattiaux Prize". To know more
