经典和量子相互作用粒子系统的随机批处理方法及统计抽样

Random Batch Methods for classical and quantum interacting particle systems and statistical samplings

Shi Jin, Lei Li

摘要:

本文综述了由$N$ -粒子组成的相互作用粒子系统的随机批处理方法(RBM),其中$N$是大粒子.这样的系统的计算成本是$O(N^2)$,这是非常昂贵的。RBM方法使用小但随机的批次,因此每个时间步长的计算成本降低到$O(N)$。在这篇文章中,我们讨论了这些方法的经典和量子系统,相应的理论,并从分子动力学,统计抽样,以代理为基础的集体行为模型,和量子蒙特卡罗方法的应用。

英文摘要:

We review the Random Batch Methods (RBM) for interacting particle systems consisting of $N$-particles, with $N$ being large. The computational cost of such systems is of $O(N^2)$, which is prohibitively expensive. The RBM methods use small but random batches so the computational cost is reduced, per time step, to $O(N)$. In this article we discuss these methods for both classical and quantum systems, the corresponding theory, and applications from molecular dynamics, statistical samplings, to agent-based models for collective behavior, and quantum Monte-Carlo methods.
