抄録

We analyze an asymptotically exact solution for the transition temperature of p-wave superconductivity near ferromagnetic criticality on the basis of three-dimensional electron systems in which scattering processes are dominated by exchange interactions with small momentum transfers. Taking into account all Feynman diagrams in the gap equation, we show that vertex corrections neglected in the conventional Eliashberg formalism enhance the dynamical retardation effect of the pairing interaction, and increase the superconducting transition temperature significantly, though they just give subleading corrections to properties of the normal state.
