Renormalized entropy production for optimal transport in jump processes: Make conservative forces optimal again
Andreas Dechant, Jann van der Meer
For continuous-space diffusion processes, there is a strong connection between conservative forces and entropy production. For a given time evolution of the system's state, the ent…

Thermodynamic bounds and error correction for faulty coarse graining
Jann van der Meer, Keiji Saito
At the nanoscale, random effects govern not only the dynamics of a physical system but may also affect its observation. This work introduces a novel paradigm for coarse graining th…

From observed transitions to hidden paths in Markov networks
Alexander M. Maier, Udo Seifert, Jann van der Meer
The number of observable degrees of freedom is typically limited in experiments. Here, we consider discrete Markov networks in which an observer has access to a few visible transit…
