Non-equilibrium systems constantly dissipate energy and produce entropy. The discoveries of Jarzynski's inequality and Crooks' fluctuation theorem over two decades ago laid the foundation for understanding thermodynamic irreversibility and entropy production at the microscopic level. Since then, there have been major developments that bound the fluctuations of entropy production and other dynamical variables using so-called Thermodynamic Uncertainty Relations (TURs). In practice, these bounds depend on how accurately a system's microscopic dynamics can be measured, which raises fundamental questions for experimental systems and systems with hidden or unknown states. In this way, bounds on irreversibility and entropy production are inextricably linked to the partial information available to an observer. In this symposium, we will hear from experts who have advanced our understanding of entropy production, thermodynamic uncertainty, and information. The format allows our speakers to start with the foundations of their subject and still get to the frontier, with plenty of time for discussion.
