Quantum Materials are electronic materials in which strong interactions between electrons lead to new electronic behavior, different from that found in conventional metals, semiconductors, magnets, and superconductors. For example, the cuprate materials which support the highest temperature superconducting state currently known, exhibit "strange metal" and "pseudogap" phases. In even more exotic cases, the electron spin and charge might move separately, as happens in carbon nanotubes and, possibly, in some frustrated magnets. Understanding such materials at a microscopic level is important, both because of the possibility of new electronic devices in the future and also because understanding such new phenomena leads to new paradigms of physical behavior which can apply to other materials, as well as to other areas of physics and science.

量子材料是电子材料，其中电子之间的强相互作用导致新的电子行为，不同于传统金属，半导体，磁铁和超导体。例如，支持目前已知的最高温度超导态的铜材料表现出“奇怪的金属”和“伪间隙”相。在更奇特的情况下，电子自旋和电荷可能会分开运动，就像在碳纳米管中发生的那样，也可能发生在一些受挫的磁铁中。在微观层面上理解这些材料是很重要的，因为未来有可能出现新的电子设备，也因为理解这些新现象会带来新的结果
