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…
Entanglement Mpemba Effect
Ruicheng Bao, Yue Liu
Generating entanglement rapidly and reliably is essential for quantum information processing, communication, and metrology. Dissipative preparation is attractive because engineered…
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…
Extreme First-Passage Time of Many Interacting Particles
Ruicheng Bao
Extreme first-passage events are broadly relevant to biological, chemical, and physical processes in which the first successful arrival determines the outcome. Existing theories ar…
Optimal Finite-Time Control of Nonreciprocal Brownian Dimers: Thermodynamic Anomaly and Multiple Transitions
Ruicheng Bao
We solve exactly a finite-time thermodynamic optimal control problem for two nonreciprocally interacting Brownian particles translated by two harmonic traps. The controller manipul…
Typical Mixing and Rare-State Bottlenecks in Open Quantum Systems
Caisheng Cheng, Ruicheng Bao
Mixing in open quantum systems is often summarized by a single worst-case time, even though that benchmark can be set by exponentially rare initial states. We show that for broad u…
