Unconventional Superconductivity in Two-Dimensional Electron Systems with Longe-Range Correlations

Abstract

Properties of superfluid states of two-dimensional electron systems with critical antiferromagnetic fluctuations are investigated. These correlations are found to result in the emergence of rapidly varying in the momentum space terms in all components of the mass operator, including the gap function $\Delta (\mathbf{p})$. It is shown that a domain, where these terms reside, shrinks with the temperature, leading to a significant difference between the temperature $T_c$, at which superconductivity is terminated, and the temperature $T^{\ast }$, where the gap in the single-particle spectrum vanishes.
