Continuous time reversal and equality in the thermodynamic uncertainty relation
نویسندگان
چکیده
We introduce a continuous time-reversal operation which connects the time-forward and time-reversed trajectories in steady state of an irreversible Markovian dynamics via family stochastic dynamics. This time reversal allows us to derive tighter version thermodynamic uncertainty relation (TUR) involving observables evaluated relative their local mean value. Moreover, realizing contains equilibrium halfway between show that this dynamics, together with appropriate choice observable, turns inequality TUR into equality. demonstrate our findings for example particle diffusing tilted periodic potential.Received 29 October 2020Revised 10 September 2021Accepted 12 2021DOI:https://doi.org/10.1103/PhysRevResearch.3.L042012Published by American Physical Society under terms Creative Commons Attribution 4.0 International license.

متن کاملThermodynamic uncertainty relation for biomolecular processes.
Biomolecular systems like molecular motors or pumps, transcription and translation machinery, and other enzymatic reactions, can be described as Markov processes on a suitable network. We show quite generally that, in a steady state, the dispersion of observables, like the number of consumed or produced molecules or the number of steps of a motor, is constrained by the thermodynamic cost of gen...
متن کاملThe Time Energy Uncertainty Relation
has been a controversial issue since the advent of quantum theory, with respect to appropriate formalisation, validity and possible meanings. Already the first formulations due to Bohr, Heisenberg, Pauli and Schrödinger are very different, as are the interpretations of the terms used. A comprehensive account of the development of this subject up to the 1980s is provided by a combination of the ...
