Quantum Materials Theory

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，与传统金属，半导体，磁体和超导体中发现的不同。 例如，支持目前已知的最高温度超导态的铜酸盐材料表现出“奇异金属”和“赝隙”相。 在更奇特的情况下，电子的自旋和电荷可能会分开运动，就像碳纳米管中发生的那样，也可能是在一些受抑的磁铁中发生的那样。 在微观水平上理解这种材料是很重要的，这既是因为未来可能出现新的电子设备，也是因为理解这种新现象会导致 物理行为的新范例，可以应用于其他材料，以及其他物理和科学领域。

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.
