Plateau Gaps of Poisson Correctors Encode Metastable Reaction Rates
Sang Yang, Zhixin Peng
Metastable reaction rates are commonly inferred from transition-state fluxes, mean first-passage times, or fitted kinetic models. We show that they are directly encoded in the plat…

Additive-Functional Approach to Transport in Periodic and Tilted Periodic Potentials
Sang Yang, Zhixin Peng
In this Letter, we clarify the physical origin of effective transport in periodic and tilted periodic systems. When Brownian dynamics is examined on the scale of a single period, t…

Effective diffusion of Brownian motion in spatially quasi-periodic noise
Sang Yang, Zhixin Peng
The effective diffusion of Brownian particles in periodic potential has been a central topic in nonequilibrium statistical physcis. A classical result is the Lifson formula which p…
