When perturbing a system, it will necessarily stay out of equilibrium for a time known as the relaxation time. Shortcutting this relaxation time may help improve nanomachines’ efficiency and force sensing scheme.
In a recent work published in Physical Review Letters, we address protocols to shortcut the equilibration time of a levitated particle submitted to a compression. We demonstrate that we can reach 17 times speed-up, and we discuss the robustness of such protocols.
