  • Title: Thermodynamic uncertainty relation for quantum work distribution: Exact case study for a perturbed oscillator.
    Author: Monnai T.
    Journal: Phys Rev E; 2022 Mar; 105(3-1):034115. PubMed ID: 35428050.
    Abstract:
    Recently, some general relations have been intensively investigated in nonequilibrium mesoscopic systems. In particular, the thermodynamic uncertainty relation (TUR) provides a general bound of the precision for the fluctuation of some currents in terms of the corresponding entropy production. On the other hand, the fluctuation of the work performed is also a significant quantity, which is supposed to satisfy TUR under some conditions, such as symmetric driving protocol. In this paper, we analytically show that the TUR holds for the work performed on an externally perturbed quantum harmonic oscillator interacting with multiple reservoirs in full quantum regime. In this manner, we evaluate how the noncommutativity affects the thermodynamic precision. We also explore its experimental accessibility.
