Evidence for an Anti-polar Phase in Normal and Superconducting States in all HTSC
It is strongly argued that high temperature superconductors (HTSC) exhibit an anti-polar phase with a long range order in both normal and superconducting states. This anti-polar phase is directly related to the onset of superconductivity in all HTSC and it is responsible for strong coupling and of two dimensionality aspect of HTSC, as it is described below.
