Abstract:
Recent progress in micro and nanofabrication enabled to design micro and nanoresonators, the mechanical properties of which are controlled by external gate voltages and electronic currents. In particular, SiN drum resonators [1] were shown to have large capacitive coupling to the gate electrode and high-quality factors, thus making them ideal candidates for further integration into circuits. Indeed, arrays of such micro and nano resonators, were predicted to synchronize due to their large mechanical non-linearities [2,3], low dissipation rate, and mutual mechanical and optomechanical coupling. This suggest to use them in innovative devices as elementary building blocks for performing neuromorphic calculations [4,5].
In this PhD project, financed by the French Agence National Recherche (ANR), we will investigate from the theoretical point of view, the mechanism of phase synchronization of arrays of SiN drum resonators, coupled to a single microwave optomechanical circuit. The goal will be to explore their capabilities as neural networks and study their behavior in the quantum regime.
The candidate for the PhD project should have a master degree in physics or obtain it before the summer 2023. A background in the condensed matter physics, quantum optics, mesoscopic physics, or statistical physics would be a plus. The starting date is flexible, and could be between Mai 2023 to October.
