Multidimensional entropic bound: Estimator of entropy production for general Langevin dynamics with an arbitrary time-dependent protocol
Sangyun Lee, Dong-Kyum Kim, Jong-Min Park +3
Entropy production (EP) is a key quantity in thermodynamics, and yet measuring EP has remained a challenging task. Here we introduce an EP estimator, called multidimensional entrop…

Perturbative Steady States of Completely Positive Quantum Master Equations
Jae Sung Lee, Joonhyun Yeo
The Lindblad form guarantees complete positivity of a Markovian quantum master equation (QME). However, its microscopic derivation for a quantum system weakly interacting with a th…

Speed limit for a highly irreversible process and tight finite-time Landauer's bound
Jae Sung Lee, Sangyun Lee, Hyukjoon Kwon +1
Landauer's bound is the minimum thermodynamic cost for erasing one bit of information. As this bound is achievable only for quasistatic processes, finite-time operation incurs addi…
