  1. Lecture: Stochastic thermodynamics and information theory

In this lecture, we will introduce the basics of stochastic thermodynamics, generalizing thermodynamic quantities like heat and entropy to describe small systems in the presence of fluctuations. This generalization has practical importance for a consistent thermodynamic description of micro- and mesoscopic system. Moreover, it can serve as a starting point for a thermodynamic framework of non-equilibrium systems. The second part of the lecture focuses on the information-theoretic formulation of the entropy production in a non-equilibrium system. We will see how the information-theoretic viewpoint can reveal universal features of out-of-equilibrium systems and how to connect it to measurable quantities.


  1. Lecture: Thermodynamic inequalities

This lecture will introduce the topic of thermodynamic inequalities. Such inequalities can be thought of as constraints on what phenomena can and cannot be observed in a given physical system. Conversely, they can also be used to obtain estimates on quantities that are difficult to measure directly. We will understand how such constraints can be derived from information-theoretic inequalities and how to apply them for thermodynamic inference. Finally, we will also see how inequalities can be “lifted” into an equality by means of a variational principle, which can in turn serve as a starting point for discovering other inequalities.
