掺杂反铁磁体的相位弦论理论

Phase String Theory for Doped Antiferromagnets

Zheng-Yu Weng

摘要:

本文简要回顾了掺杂反铁磁体的相位弦论理论的最新进展。这样的理论是建立在一个奇异的相位弦效应引起的掺杂反铁磁体中的空穴的运动,这是一个精确的性质的t-J模型决定了新的竞争之间的电荷和自旋自由度。一个全球性的相图,包括反铁磁,超导,上下赝能隙,高温"正常"相,以及这些阶段的一系列异常的物理性质,将作为自洽和系统的相位弦论的后果。

英文摘要:

The recent developments of the phase string theory for doped antiferromagnets will be briefly reviewed. Such theory is built upon a singular phase string effect induced by the motion of holes in a doped antiferromagnet, which as a precise property of the t-J model dictates the novel competition between the charge and spin degrees of freedom. A global phase diagram including the antiferromagnetic, superconducting, lower and upper pseudogap, and high-temperature "normal" phases, as well as a series of anomalous physical properties of these phases will be presented as the self-consistent and systematic consequences of the phase string theory.
