摘要:

利用精确的数值解和精确的远红外椭偏测量研究了弱空穴掺杂高温超导体中的电荷动力学.实验观察到的红外光谱中的两个电子带可以根据电子相关和电子-声子相互作用之间的相互作用来识别,解决了中红外带长期存在的谜团。

英文摘要:

The charge dynamics in weakly hole doped high temperature superconductors is studied in terms of the accurate numerical solution to a model of a single hole interacting with a quantum lattice in an antiferromagnetic background, and accurate far-infrared ellipsometry measurements. The experimentally observed two electronic bands in the infrared spectrum can be identified in terms of the interplay between the electron correlation and electron-phonon interaction resolving the long standing mystery of the mid-infrared band.
