x_opt and x_c in Cuprate Superconductors
Jürgen Röhler
The characteristic hole concentrations x_opt = 0.16 and x_c = 0.19 in the under- to overdoped transition regime of cuprate superconductors are shown to be intimately interrelated b…
The bulge in the basal plane area of cuprate superconductors - evidence for 3a singlet hole pairs
Jürgen Röhler
The bulge in the doping dependence of the basal plane area in hole doped cuprate superconductors is connected with a non-double-occupancy constraint for the oxygen cages in the CuO…
The bulge in the basal plane area of cuprate superconductors
J. Röhler
The bulge in the doping dependence of the basal plane area of cuprate superconductors is shown to be an effect of the particular inhomogenous electronic structure created by the de…
On self-protecting singlets in cuprate superconductors
J. Röhler
The basal area (Cu-Cu grid) of the cuprate superconductors not only tends to shrink on hole doping, as expected from single electron quantum chemistry, but exhibits also an electro…
c-Axis Intra-Layer Couplings in the CuO_2 Planes of High-T_c Cuprates
J. Röhler
We discuss the static deformations of the doped CuO_2 lattices in YBa_2Cu_3O_x. Intrinsic lattice effects driven by the strong correlations of the electron system are separated fro…
Plane dimpling and Cu 4s hybridization in YBa_2Cu_3O_x
J. Röhler
Oxygen doping dimples the CuO_2 planes of YBa_2Cu_3O_{6.8-6.92} by displacing copper normal to the planes and further towards Ba. The correlated oxygen displacements, however, are…
