The second law of Thermodynamics imposes severe limitations to the energetic cost of manipulations of physical systems. The minimal cost is only achieved in principle for extremely slow processes which are not feasible in real conditions. Thus, it is mandatory to approach the following problem: which is the thermodynamic process that, in finite time, minimizes the energetic cost of a give…

The search for efficient control of physical systems dates back to Carnot's work on heat engines in the XIX century. Nowadays, we seek for efficient control of complex quantum systems as, for instance, the network of magnetic fluxes of quantum computers called quantum annealers. One important criterion to decide about how efficient are the tasks performed by these contemporary machines is…
Recent experimental developments have allowed high control on quantum systems at the nanoscale. In some circumstances, it is even possible to have experimental access to the quantum state of these systems of few particles. Along with other factors, this has stimulated the development of an informational approach to the non-equilibrium thermodynamics of these systems. Informational quantit…
The implementation of effective adiabatic (or quasistatic) dynamics in finite time is one of the main goals in the fields of quantum control and quantum thermodynamics. The reason for that is simple: avoiding transitions helps to decrease the energetic cost of the manipulation but also block the effects of external noise. The different techniques that aim to reach this goal, the so-called…
Single molecules experiments such as optical tweezers and atomic force microscopy have led to great achievements in the field of non-equilibrium thermodynamics in the last decades. In particular, this project focus on those experiments investigating the efficiency of finite-time microscopic heat engines, in contrast to the textbook examples of quasi-static cycles. Our goals are (i) to cha…
Recently developed experimental techniques have provided means of controlling and trapping quantum systems at the nanoscale. In some circumstances, it is even possible to have experimental access to the quantum state of these systems. This fact has stimulated the development of an informational approach of the non-equilibrium thermodynamics of these systems. Informational quantities as th…
Single-molecule experiments using optical tweezers or atomic force microscopy have led to great advances in the field of out-of-equilibrium thermodynamics in the last decades. Among them, we highlight in this project the research on the efficiency of nanoscopic heat engines which naturally operate in finite time and hence contrast with the quasistatic idealized cycles of textbooks on Ther…

Thermally isolated systems are a highly idealized situation. Nevertheless, they are a theoretical setup that helps to (i) introduce the fundamental laws and symmetries that we believe to be ultimately valid and (ii) derive predictions for a part of the isolated system without relying on assumptions of weak coupling between this part and the rest. The aim of this proposal is to complement …
One of the current problems in Thermodynamics is to obtain protocols that minimize energy dissipation when a given time-finite thermodynamic process is performed. On the other hand, the techniques used in literature to achieve this end lack generality, either because they do not enter arbitrarily far-from-equilibrium regions or because they are unable to deal with general systems, thus re…
The statistical thermodynamics of far from equilibrium systems has undergone an amazing development within the last years. These recent results reached far beyond linear response theory and replaced the usual thermodynamic inequalities between work and free energy by equalities. Nevertheless, these new relations were recently extended to the context of thermodynamic processes with feedbac…
