Non-equilibrium systems are numerous and seemingly very different from each other. They are nowadays realized in the lab with various tools and at many different scales, enabling their study, and exploring their specific characteristics as well as universal properties.
In this talk, I will present how the framework of information engines (IE), can be implemented within such non-equilibrium systems and propose to use IEs as a platform to study them. We build a colloidal IE converting information into pressure obeying, at equilibrium, a universal relation for the extracted work. In contrast, a Szilard engine based on macroscopic active matter extracts large amounts of work due to giant number fluctuations, common in non-equilibrium active matter. Finally, we demonstrate how the framework of IE can be applied to Brownian systems undergoing stochastic resetting (SR). This latter example of a non-equilibrium state is of foremost importance in the field of the search process but seemingly unrelated to IE. However, by using the ideas of Szilard’s engine, we design a protocol implementing SR in an optical trap at the lowest reversible thermodynamic cost.
