Quasiparticle dynamics and in-plane anisotropy in $Y B a_{2} C u_{3} O_{y}$ system near onset of superconductivity

arXiv:cond-mat/0408097 · doi:10.1103/PhysRevB.70.014518

Abstract

We report on an infrared study of carrier dynamics within the CuO $_{2}$ planes in heavily underdoped detwinned single crystals of YBa $_{2}$ Cu $_{3}$ O. In an effort to reveal the electronic structure near the onset of superconductivity, we investigate the strong anisotropy of the electromagnetic response due to an enhancement of the scattering rate along the a-axis. We propose that the origin of this anisotropy is related to a modulation of the electron density within the CuO $_{2}$ planes.
