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…

Disorder effects in electronic structure of substituted transition metal compounds
D. D. Sarma, A. Chainani, S. R. Krishnakumar +9
Investigating LaNi(1-x)M(x)O3 (M = Mn and Fe), we identify a characteristic evolution of the spectral function with increasing disorder in presence of strong interaction effects ac…
