Impact of nonlinear electron-phonon coupling in MgB2 on high TC superconductivity
The processes of nonlinear electron-phonon coupling in superconductors with two-band electronic structure are considered. It is shown that the mechanism of two-phonon exchange between the carriers has a considerable impact on increasing of TC of superconductivity in MgB2 compound...

| Sumario: | The processes of nonlinear electron-phonon coupling in superconductors with two-band
electronic structure are considered. It is shown that the mechanism of two-phonon exchange
between the carriers has a considerable impact on increasing of TC of superconductivity in
MgB2 compound. |
