摘要

本研究在先前磁碟阵列（MDAs）研究的基础上，探讨霍尔输运现象。我们使用类似于洛伦兹等离子体的碰撞模型来研究带电粒子的动力学。以前，我们推导了各向同性和单动能条件下的输运系数。在本研究中，我们采用傅里叶变换增强的各向异性框架，并采用局部麦克斯韦分布函数。这些假设使我们能够计算霍尔扩散率、电导率和热霍尔导电性张量。我们的发现有助于更深入地理解磁盘阵列和手性有源系统中的霍尔输运。

Maxwellian Distribution-Based Hall Transport Coefficients for Charged Particles in Magnetic Disk Array.

This study explores Hall transport phenomena by expanding upon prior research on magnetic disk arrays (MDAs). We examine the dynamics of charged particles using collision models akin to those in Lorentzian plasma. Previously, we derived transport coefficients under isotropic and mono-kinetic conditions. In this study, we adopt an anisotropic framework, enhanced by Fourier transformation, and employ the local Maxwellian distribution function. These assumptions allow us to calculate the Hall diffusivity, electrical conductivity, and thermal Hall conductivity tensors. Our findings contribute to a deeper understanding of the Hall transport in magnetic disk arrays and chiral active systems.

期刊介绍： Entropy (ISSN 1099-4300), an international and interdisciplinary journal of entropy and information studies, publishes reviews, regular research papers and short notes. Our aim is to encourage scientists to publish as much as possible their theoretical and experimental details. There is no restriction on the length of the papers. If there are computation and the experiment, the details must be provided so that the results can be reproduced.
