Memory-aware feedback enhances power in active information engines
Sehoon Bahng, Jae Sung Lee, Cheol-Min Ghim
We study an information engine operating in an active bath, where a Brownian particle confined in a harmonic trap undergoes feedback-driven displacement cycles. Unlike thermal envi…

Discrete-time thermodynamic speed limit
Sangyun Lee, Jae Sung Lee, Jong-Min Park
As a fundamental thermodynamic principle, speed limits reveal the lower bound of entropy production (EP) required for a system to transition from a given initial state to a final s…

Fluctuation-response inequalities for kinetic and entropic perturbations
Euijoon Kwon, Hyun-Myung Chun, Hyunggyu Park +1
We derive fluctuation-response inequalities for Markov jump processes that link the fluctuations of general observables to the response to perturbations in the transition rates wit…
