Learning Stochastic Dynamics with Statistics-Informed Neural Network

1 code implementation • 24 Feb 2022 • Yuanran Zhu, Yu-Hang Tang, Changho Kim

We devise mechanisms for training the neural network model to reproduce the correct \emph{statistical} behavior of a target stochastic process.

Momentum fluctuations in coarse grained systems

no code implementations • 17 Dec 2020 • M. Reza Parsa, Changho Kim, Alexander J. Wagner

We show that particularly the fluctuating properties of common definitions of momentum in coarse grained methods like lattice gas and lattice Boltzmann do not agree with a fundamental definition of momentum.

Efficient Reactive Brownian Dynamics

2 code implementations • 5 Oct 2017 • Aleksandar Donev, Chiao-Yu Yang, Changho Kim

We develop a Split Reactive Brownian Dynamics (SRBD) algorithm for particle simulations of reaction-diffusion systems based on the Doi or volume reactivity model, in which pairs of particles react with a specified Poisson rate if they are closer than a chosen reactive distance.
