  • Understanding the thermodynamic cost of resetting via time-varying harmonic traps has many parallels to the finite-time Landauer erasure principle, which sets a bound on the energy cost of information erasure over finite durations. In this study, the authors examine the thermodynamic costs of such a setup by deriving a moment generating function for the work cost of recurrently changing the trap stiffness in finite-time, thereby obtaining the cost of erasing a non-equilibrium state over finite durations.

  • Thermal fluctuations play a crucial role in non-equilibrium phenomena at microscopic length scales, making it challenging to analyse and interpret experimental data. Here, the authors demonstrate that the short-time thermodynamic uncertainty relation inference scheme can estimate the entropy production rate for a colloidal particle in time-varying potentials and with background flows determined by the presence of a microbubble.

  • While methods for estimating the entropy production rate of a stationary process are relatively well established, this is still a challenge in non-stationary conditions. Here, the authors propose a scheme to infer the exact value of the time-dependent entropy production rate as well as entropy production along with single realizations directly from trajectory data.
