Abstract

Traditionally, thermodynamics has been applied almost exclusively to macroscopic (and thus classical) systems. However, recently it has been recently realized that it can be used to provide a new way of assessing and exploiting dynamics occurring at the microscopic scale, where thermal fluctuations start competing with quantum effects. Such interplay, which makes necessary a fundamental reformulation of classical concepts of thermodynamics, such as work and heat, is also responsible for the emergence of a whole new set of advantages of a genuine quantum nature. This emerging field is known as non-equilibrium quantum thermodynamics (NEQT). ln this project we address one of the essential concepts in NEQT, namely that of irreversibly. We propose to construct theoretically new measures of entropy production and apply them to paradigmatic (and experimentally relevant) problems in the fields of quantum physics. (AU)
