Gauge Model of High-Tc Superconductivity

A simple gauge model of superconductivity is presented. The seagull vertex term of this gauge model gives an attractive potential between electrons for the forming of Cooper pairs of superconductivity. This gauge model gives a unified description of superconductivity and magnetism including antiferromagnetism, pseudogap phenomenon, stripes phenomenon, paramagnetic Meissner effect, Type I and Type II supeconductivity and high-T-c superconductivity. The doping mechanism of superconductivity is found. It is shown that the critical temperature T-c is related to the ionization energies of elements and can be computed by a formula of T-c. For the high-T-c superconductors such as La2-xSrxCuO4, Y Ba2Cu3O7, and MgB2, the computational results of T-c agree with the experimental results.
