Effective Radius of a Discrete Moving Polymer
Jiaming Chen
We present a discrete model for a weakly self-avoiding polymer of intrinsic length governed by a discrete heat equation perturbed by Gaussian noise. By introducing a renormaliz…

Fisher information and trajectorial interpretation to the Itô--Langevin relative entropy dissipation
Jiaming Chen
The dissipation phenomena of relative entropy from an Itô--Langevin dynamical system is a classic topic from stochastic analysis. Relying on the time-reversal of diffusions, a nov…
