Electronic band structure, frozen phonons and some approximations to the electron-phonon interactions for the "infinite layer" cuprates CaCuO2 and SrCuO2 are studied by the full potential linear muffin tin orbital method (FP-LMTO). Differences and similarities with other cuprates studied by the same
Total energy local density determinations of the effects of pressure on the (Srt\_xCax h\_yCuO2 infinite layer (IL) Tc ffi 110 K superconductor show, that the compressibility is highly anisotropic. Surprisingly , the energy location of the van Hove singularity (vHs) moves towards EF with pressure, t
