Direct route to thermodynamic uncertainty relations and their saturation

C Dieball, A Godec - Physical Review Letters, 2023 - APS
Thermodynamic uncertainty relations (TURs) bound the dissipation in nonequilibrium
systems from below by fluctuations of an observed current. Contrasting the elaborate …

Coarse graining empirical densities and currents in continuous-space steady states

C Dieball, A Godec - Physical Review Research, 2022 - APS
We present the conceptual and technical background required to describe and understand
