A calculation of Eliashberg equations for superconducting phase under the ultra-high magnetic field of strong coupling cases in 2 and 3 dimensional systems

The estimation of Tc for the superconducting phase under the ultra-high magnetic field is discussed on the basis of numerical calculation by the use of the expression of Eliashberg equations for strong coupling theory. The essential effect of the retardation of the interaction by phonons on making the gap is pointed out in comparison between 2 and 3 dimensional systems.
