Periodic Reporting for period 4 - QnanoMECA (Quantum Optomechanics with a levitating nanoparticle)
Reporting period: 2020-06-01 to 2020-09-30
A second aspect of our work related to exploring how the concept of levitation optomechanics could benefit from a more efficient interaction of the levitated particle with light, enabled by the latest advances in nano-optics. Through nano-structuring of optical materials nano-optics enables to concentrate light well-beyond what is allowed by conventional optics using lenses and mirrors. By exploiting the enhanced light matter-interaction resulting from the coupling of the levitated particle to a nano-optical cavity, we were able to reach unprecedented optomechanical regimes foreseen to benefit, for instance, the development of ultra-sensitive inertial sensors.
Last but not least, the third part of our work focused on extending levitation optomechanics to nanoparticles hosting quantum emitters. The properties of the latter indeed offer, through the use of a specific light, further control over the particle motion. To this aim, we successfully developed a novel hybrid levitation platform, combining optical and electric forces, which paves the way to the future generation of optomechanical experiments.
QnanoMECA has been overall very successful by meeting all original objectives. The scientific outcome has led to more than ten publications in prestigious scientific journals (three additional manuscripts have been already submitted and two other ones are in preparation) and multiple invited talks in international conferences.
