Quasiparticle dynamics and in-plane anisotropy in $YB{a}_{2}C{u}_3{O}_y$ system near onset of superconductivity

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.
