| Control of out-of-equilibrium dynamics for levitated nanoparticle |
| Speaker: | Ines Ben-Yedder (LuMIn, CNRS, Université Paris-Saclay) |
| Abstract: | In this presentation, I will present my work to understand and control out-of-equilibrium thermodynamics at the nanoscale. My research falls within this context, using optical tweezers to trap silica nanoparticle levitating in vacuum. This particle is sensitive to fluctuations through its Brownian motion and constitutes an excellent model for the experimental study of stochastic processes.
First, I will explore optimization of finite-time thermodynamic transformations in the underdamped regime. By dynamically modulating the stiffness of the optical potential, I achieved precise control over the particle's dynamics, enabling the realization of an optimal decompression protocol with bounded stiffness [1].
To extend the control on non-equilibrium thermodynamics beyond the harmonic approximation, I will then present my work toward the generation of an arbitrary potential. I will discuss the |
