Mapping current and activity fluctuations in exclusion processes: consequences and open questions
Mapping current and activity fluctuations in exclusion processes: consequences and open questions
Considering the large deviations of activity and current in the Asymmetric Simple Exclusion Process (ASEP), we show that there exists a non-trivial correspondence between the joint scaled cumulant generating functions of activity and current of two ASEPs with different parameters. This mapping is obtained by applying a similarity transform on …
