Circular photogalvanics study of BSCCO high temperature superconductors

ORAL

Abstract

Recent studies have reported that bulk inversion symmetry may be broken inside the pseudogap region of the phase diagram in YBa2Cu3Oy single crystals. Here, we report signatures of inversion symmetry breaking in another family of cuprate high temperature superconductors, Bi2Sr2CaCu2O8+δ, using circular photogalvanic measurements.
