Anisotropy of non-equilibrium quasi-particle dynamics in single-crystal YBa2Cu3O7-delta

Abstract:
We report measurements of non-equilibrium quasi-particle dynamics in detwinned single-crystals of YBCO using femtosecond time-resolved reflectance. Distinct contributions arising from the a- and b-axis response are separately identified for the first time using polarised light. The a-axis component is sensitive to carrier correlation in the superconducting state, and appears to be a common feature of many high-T-c superconductors; the b-axis component exhibits distinctive pseudogap behaviour.
