Hyperaccurate bounds in discrete-state Markovian systems
Hyperaccurate bounds in discrete-state Markovian systems
Abstract Generalized empirical currents represent a vast class of thermodynamic observables of mesoscopic systems. Their fluctuations satisfy the thermodynamic uncertainty relations (TURs), as they can be bounded by the average entropy production. Here, we derive a general closed expression for the hyperaccurate current in discrete-state Markovian systems, i.e. the one …
