Assessing the validity of the thermodynamic uncertainty relation in quantum systems

BK Agarwalla, D Segal - Physical Review B, 2018 - APS
We examine the so-called thermodynamic uncertainty relation (TUR), a cost-precision trade-
off relationship in transport systems. Based on the fluctuation symmetry, we derive a …
