| الوصف: | A diffusive process that is reset to its origin at random times, so-called stochastic resetting (SR) is an ubiquitous expedient in many natural systems \cite{Evans2011}. Beyond its ability to improve efficiency of target searching, SR is a true non-equilibrium thermodynamic process that brings forward new and challenging questions \cite{Fuchs2016}. Here, we experimentally implement SR within a time-dependent optical trapping potential and give a quantitative assessment of its thermodynamics. We show in particular that SR operates as a Maxwell demon, converting heat into work from a single bath continuously and without feedback \cite{Roldan2014, Ciliberto2019}. Such a demon is the manifestation of the constant erasure of information at play in resetting that, in our experiments, takes the form of a protocol. By tailoring this protocol, we can bring the demon down to its minimal energetic cost, the Landauer bound \cite{Lutz2015}. In addition, we reveal that the individual trajectories forming this autonomous demon all break ergodicity and thereby demonstrate the non-ergodic nature of the demon's \textit{modus operandi}.
