Much of what we understand about simple metals and semiconductors is based on a single-particle picture. Once we determine what one electron does, then any macroscopic current or response is determined by this single-particle behaviour, with slight modifications to account for the statistics of the many electrons. In recent decades, however, researchers have discovered more and more materials that support conduction --- that is, they show metallic behaviour, and turn out to have extremely interesting properties. By way of example, a class of the high temperature cuprate materials, epitomized by La

我们对简单金属和半导体的大部分理解都是基于单粒子图像。一旦我们确定了一个电子的作用，那么任何宏观电流或响应都是由这个单粒子行为决定的，只需要稍微修改一下就可以解释许多电子的统计数据。然而，近几十年来，研究人员发现了越来越多的支持传导的材料，也就是说，它们表现出金属行为，并具有非常有趣的性质。举例来说，一类高温铜酸盐材料，由La
