软物质非均匀性的非高斯信息

Non Gaussian information of heterogeneity in Soft Matter

Rahul Dandekar, Soumyakanti Bose, Suman Dutta

摘要:

在软物质中普遍存在着非高斯分子位移分布形式的异质结动力学。我们解决了这种异质性的量化使用的实际位移分布和其最近的高斯估计之间的距离的信息理论的措施。我们探讨这种措施的有用性在两个通用的场景中的随机游走在异构介质。我们表明,我们提出的措施导致一个更好的量化非高斯比传统的矩比的基础上。

英文摘要:

Heterogeneity in dynamics in the form of non-Gaussian molecular displacement distributions appears ubiquitously in soft matter. We address the quantification of such heterogeneity using an information-theoretic measure of the distance between the actual displacement distribution and its nearest Gaussian estimation. We explore the usefulness of this measure in two generic scenarios of random walkers in heterogeneous media. We show that our proposed measure leads to a better quantification of non-Gaussianity than the conventional ones based on moment ratios.
