本文概述了自旋电子学中的规范场，重点讨论了它们的起源和物理后果。重要的主题，如与绝热量子演化相关的贝里规范场，以及由其他非绝热考虑引起的规范场，被讨论。我们在三个空间，即实空间、动量空间和时间，采用半经典的方法研究规范场的外观和效果。我们抓住机会研究其他“类自旋”系统，包括石墨烯、拓扑绝缘体、磁振学和光子学，这些系统强调规范场的普遍性和重要性。我们的目标是提供一个直观的和教学的见解，规范场在自旋输运中所起的作用。(C) 2011年美国物理研究所。(doi: 10.1063/1.3665219)
We present an overview of gauge fields in spintronics, focusing on their origin and physical consequences. Important topics, such as the Berry gauge field associated with adiabatic quantum evolution as well as gauge fields arising from other non-adiabatic considerations, are discussed. We examine the appearance and effects of gauge fields across three spaces, namely real-space, momentum-space, and time, taking on a largely semiclassical approach. We seize the opportunity to study other "spin-like" systems, including graphene, topological insulators, magnonics, and photonics, which emphasize the ubiquity and importance of gauge fields. We aim to provide an intuitive and pedagogical insight into the role played by gauge fields in spin transport. (C) 2011 American Institute of Physics. [doi: 10.1063/1.3665219]
