AI 中文摘要
这些是为2026年宾夕法尼亚州立大学CTEQ暑期学校的一个短期讲座系列编写的讲座笔记。笔记采用对话式和非正式风格。其目的是在近期实验的背景下，介绍和回顾关于维格纳晶体（二维电子系统的固相）的一些新旧观点。特别强调了维格纳晶体的半经典描述、其量子熔化转变、自旋序以及维格纳晶体可被贝里曲率修改的方式。
英文摘要
These are lecture notes created for a short lecture series at the 2026 CTEQ Summer School at Penn State. They are written in a conversational and informal style. The goal of these notes is to introduce and review a smattering of old and new ideas about the Wigner crystal (the solid phase of the two-dimensional electron system) in the context of recent experiments. Particular emphasis is given to the semiclassical description of the Wigner crystal, its quantum melting transition, its spin order, and the ways in which the Wigner crystal can be modified by Berry curvature.
