Abstract

The model is based on a mirror symmetry breaking second order phase transition leading to a pairing between a free charge carriers and a free mirror charge carriers. This approach gives a unified description of low and high Tc superconductivity with a point of view differing from that of BCS theory.The material's crystal structure symmetry is the key to understand the mechanism of pairing by introducing a mirror plane polarization effect in lattice as it is described below.
