A pedestrian's approach to large deviations in semi-Markov processes with an application to entropy production
Alexander M. Maier, Jonas H. Fritz, Udo Seifert
Semi-Markov processes play an important role in the effective description of partially accessible systems in stochastic thermodynamics. They occur, for instance, in coarse-graining…

Entropy estimation for partially accessible Markov networks based on imperfect observations: Role of finite resolution and finite statistics
Jonas H. Fritz, Benjamin Ertel, Udo Seifert
Estimating entropy production from real observation data can be difficult due to finite resolution in both space and time and finite measurement statistics. We characterize the sta…

Stochastic thermodynamics of chemical reactions coupled to finite reservoirs: A case study for the Brusselator
Jonas H. Fritz, Basile Nguyen, Udo Seifert
Biomolecular processes are typically modeled using chemical reaction networks coupled to infinitely large chemical reservoirs. A difference in chemical potential between these rese…
