Shortcuts To Adiabaticity for Lévy processes in harmonic traps
Marco Baldovin, David Guéry-Odelin, Emmanuel Trizac
Lévy stochastic processes, with noise distributed according to a Lévy stable distribution, are ubiquitous in science. Focusing on the case of a particle trapped in an external harm…

Qi Zhang, Xi Chen, David Guéry-Odelin
With the advent of quantum technologies, control issues are becoming increasingly important. In this article, we address the control in phase space under a global constraint provid…
Accelerating the heat diffusion: fast thermal relaxation of a microcantilever
Basile Pottier, Carlos Plata, Emmanuel Trizac +2
In most systems, thermal diffusion is intrinsically slow with respect to mechanical relaxation. We devise here a generic approach to accelerate the relaxation of the temperature fi…
