Abstract
We present a purely electronic mechanism for superconductivity in a disordered Fermi liquid. It is based on long-time-tail effects in electronic correlations, is strongest in two-dimensional systems, and leads to triplet even-parity pairing. The mechanism has a potential for high transition temperatures and high critical fields. The superconducting state shows interesting features, including a short coherence length, and a gapless tunneling density of states.
