Gap symmetry and charge density excitations in high-Tc superconductors with extended saddle points in electron spectrum
It is shown that the strong anisotropy of the one-particle electron spectrum, due to the presence of extended saddle-point features (ESPF) close to the Fermi level in the hole-type cuprates YBCO and BSCCO, leads to the occurrence of a low-frequency peak in the spectral function of the charge dens...
