Exact First-Passage Time Response Theory from Steady-State Response
Ruicheng Bao, Shiling Liang
The mean first-passage time (MFPT) provides a universal temporal measure of transport, reaction, search, and switching processes in physical, chemical, and biological systems. Unde…

A Universal Control Budget for First-Passage Kinetics
Shiling Liang, Ruicheng Bao
The first-passage time is the natural observable of reaction completion, yet how its mean responds to a rate change has lacked a general constraint. We show that the logarithmic se…

Nonlinear Response Identities and Bounds for Nonequilibrium Steady States
Ruicheng Bao, Shiling Liang
Understanding how systems respond to external perturbations is fundamental to statistical physics. For systems far from equilibrium, a general framework for response remains elusiv…
