We cordially invite you to the lecture by Dr. James Millen (Department of Physics Faculty of Natural and Mathematical Sciences King's College London), which will take place on 29.5.2024, 10:00 in the lecture hall of the Institute of Scientific Instruments of the CAS.

Abstract

Neuromorphic detection and control of interacting arrays of microparticles
Microparticles levitated in a vacuum can be used as precision sensors and for probing fundamental physics. It is an exciting extension to utilize arrays of levitated microparticles, so cancel out common-noise in sensors, to allow directional detection of forces, and to engineer complex collective states - even potentially in the quantum regime. It is challenging to detect the motion of arrays of objects, and even more so to read-out their motion in real-time. We use a novel detection technique to achieve this: neuromorphic, or event-based, imaging (EBI). EBI enables us to detect 10s of particles and read-out their motion at 1 MHz. We present two applications of this technology: firstly we detect and cool arrays of interacting particles, secondly we track a single particle with high dynamic range and resolution for studies of fundamental thermodynamics.
