项目摘要
In this research project, we performed STM/STS experiments under magnetic fields and pump-probe optical experiments in one of the typical high-Tc cuprates Bi2212 to clarify the origin of the electronic charge order accompanied by a pseudogap and its relation to the high-Tc superconductivity. STM/STS experiments suggested that the electronic charge order will be understood in terms of the charge-spin stripes model, and dynamically fluctuating in nature. In pump-probe optical experiments, furthermore, it was found that the electronic charge order and pseudogap do not only compete with but also is needed for the high-Tc superconductivity. Employing these results, we pointed out that the fluctuating stripes would be responsible for the formation of high-Tc superconductivity.
在本研究项目中,我们在一种典型的高温铜酸盐Bi2212中进行了磁场下的STM/STS实验和泵浦探针光学实验,以阐明伴随赝能隙的电子电荷序的起源及其与高温的关系。 Tc 超导性。 STM/STS 实验表明,电子电荷顺序可以根据电荷自旋条纹模型来理解,并且本质上是动态波动的。此外,在泵浦探测光学实验中,人们发现电子电荷序和赝能隙不仅与高温超导相竞争,而且是高温超导所必需的。利用这些结果,我们指出波动条纹可能是高温超导性形成的原因。
