[Théorie classique et quantique du refroidissement photothermique en cavité dʼun oscillateur mécanique]
Les effets photothermiques permettent un couplage optomécanique très efficace entre degrés de liberté mécaniques et photons. Dans le contexte du refroidissement en cavité dʼun oscillateur mécanique, une question reste ouverte : savoir si lʼon peut atteindre lʼétat quantique fondamental de lʼoscillateur à lʼaide dʼun refroidissement photothermique ? Ici nous répondons à cette question par deux traitements théoriques complémentaires : lʼun classique, lʼautre quantique. Les deux approches nous portent à conclure que : dʼabord lʼétat fondamental peut en effet être atteint par refroidissement photothermique, ensuite il peut être atteint dans un régime de faible désaccord de cavité, ce qui permet à une grande partie des photons incidents dʼentrer dans la cavité.
Photothermal effects allow very efficient optomechanical coupling between mechanical degrees of freedom and photons. In the context of cavity cooling of a mechanical oscillator, the question of if the quantum ground-state of the oscillator can be reached using photothermal back-action has been debated and remains an open question. Here we address this problem by complementary classical and quantum calculations. Both lead us to conclude that: first, the ground-state can indeed be reached using photothermal cavity cooling, second, it can be reached in a regime where the cavity detuning is small allowing a large amount of incident photons to enter the cavity.
