摘要

通过对正态分布函数的反复迭代，数值实现了具有随机分布高斯粗糙度的二维势能面。随后研究了布朗粒子在这种二维随机PES上的扩散过程，以验证其正确性。结果表明，本文提出的二维随机PES构造策略是合理、正确的。粒子轨迹跟踪的结果显示了典型的标准布朗运动的动力学模式。

Numerical realization of a two-dimensional potential energy surface with randomly distributed Gaussian roughness

A two-dimensional (2D) potential energy surface (PES) with randomly distributed Gaussian roughness is realized numerically by repeatedly iterating the function of a normal distribution. The process of a Brownian particle diffusing on such a 2D random PES is studied subsequently to check its correctness. Results show that the strategy of the 2D random PES constructing presented in this work is reasonable and correct. The outcome of trajectory tracking of the particle reveals a typical dynamic pattern of standard Brownian motion.

期刊介绍： Physica A: Statistical Mechanics and its Applications Recognized by the European Physical Society Physica A publishes research in the field of statistical mechanics and its applications. Statistical mechanics sets out to explain the behaviour of macroscopic systems by studying the statistical properties of their microscopic constituents. Applications of the techniques of statistical mechanics are widespread, and include: applications to physical systems such as solids, liquids and gases; applications to chemical and biological systems (colloids, interfaces, complex fluids, polymers and biopolymers, cell physics); and other interdisciplinary applications to for instance biological, economical and sociological systems.
