Localisation of doped holes in edge-shared CuO_2 chain cuprates: consequences for dynamic spectral weight transfer

Z. Hu, S. -L. Drechsler, J. Malek +9

We present a joint experimental and theoretical study of the electronic structure of the cuprate chain systems A_(1-x)CuO_2 (A=Ca,Sr,Ba), as measured using O-K and Cu-L_3 x-ray abs…
