对“Bi2201赝能隙态中的粒子-空穴对称性破缺“的评论

Comment to: "Particle-hole symmetry breaking in the pseudogap state of Bi2201"

Itai Panas

摘要:

Shen等人[1]最近报道了Pb-Bi 2201的ARPES数据,揭示了粒子-空穴对称性破缺和明显的光谱增宽,他们认为这表明在赝能隙开口处没有长程序的空间对称性破缺。这里演示了如何解释他们的结果,以反映静态和动态不均匀的晶体场导致带间传输的孔冷却时低于T*。可能的相关性形成的载流子的不均匀性进行了讨论,并提出了一个量子化学的理解高温超导的角度。

英文摘要:

Shen et al. [1] recently reported on ARPES data from Pb-Bi2201 revealing both particle-hole symmetry breaking and pronounced spectral broadening, which they interpret to be indicative of spatial symmetry breaking without long-range order at the opening of the pseudogap. Here is demonstrated how their results could be interpreted to reflect static and dynamic inhomogeneous crystal fields causing inter-band transfer of holes upon cooling below T*. Possible relevance to formation of charge carrier inhomogeneities is discussed, and put in perspective of a proposed quantum chemical understanding of HTS.
