Title: Título: Optimal Control and State Estimation of Optically
Levitated Nanoparticles near the Heisenberg Limit.
Abstract: Optically levitated nanoparticles in ultra-high vacuum offer a powerful experimental platform for exploring fundamental physics, including stochastic thermodynamics, nonlinear dynamics, searches for
new particles and forces, and tests of quantum mechanics. Many of these applications rely on preparing the nanoparticle in its motional ground state, a goal achieved through feedback control operating at the Heisenberg limit. In this talk, I will demonstrate how to reach this limit, optimally estimate the particle’s state using a Kalman filter, and apply optimal actuation to drive it to its ground state.
