The Memory Hidden in Response Fluctuations: Trajectory-Level Fluctuation-Response Theory and Inequalities for Non-Markovian Jump Dynamics
Jiming Zheng, Zhiyue Lu
Modern experiments often record nonequilibrium dynamics as sequences of discrete events whose rates depend on the realized past. We develop a fluctuation-response theory for such n…

Mutual Linearity in Nonequilibrium Langevin Dynamics
Jiming Zheng, Zhiyue Lu
Understanding how nonequilibrium systems respond to perturbations is a central challenge in physics. In this work, we establish mutual linearity in nonequilibrium overdamped Langev…

Mutual Linearity in and out of Stationarity for Markov Jump Processes: A Trajectory-Based Approach
Jiming Zheng, Zhiyue Lu
Nonequilibrium response theory is a fundamental framework for understanding how physical systems respond to perturbations. Recently, a mutual linearity has been discovered for Mark…
