Description

Location: Room 5209

The thermodynamics of quantum systems is currently a very active field due to the current interest in future quantum technologies. It is important to understand what are the unique quantum contributions to quantities such as work and entropy production. This talk will focus on understanding two particular
effects. In the first part of the talk I will concentrate on how in a non-equilibrium protocol that the work dissipated is related to the relative entropy of
coherence. An operational measure in quantum information theory. In addition, I will mention extensions to the open system case.

In the second part of the talk I shall investigate how the presence of quantum correlations can influence work extraction in closed quantum systems. We will consider a bipartite quantum system and we show that it is possible to optimise the process of work extraction, thanks to the correlations between the two parts of the system, by using an appropriate feedback protocol based on the concept of ergotropy.
