MULTI-GAP SUPERCONDUCTIVITY IN MgB_2

摘要

We using our two-band model for the explanation of two coupled superconductivity gaps for MgB_2.To study the effect of the increasing of T_c in MgB_2 due to the enhanced interband pairing scattering. We have proposed two channel scenario of superconductivity: the conventional channel which is connected with BCS mechanism in different zone and the unconventional channel which describes the transfer or tunneling of Cooper pair between two bands.
