Odd-frequency spin-triplet instability in disordered electron liquid — •Vladimir Zyuzin1 and Alexander Finkel'stein2 — 1Texas A&M University, Nordita — 2Texas A&M University
We theoretically consider a two-dimensional disordered conductor in the vicinity to the superconducting phase destroyed by a magnetic field. We find that a point of ending the superconductivity is a quantum critical point separating the conventional superconducting phase from a state with the odd-frequency spin-triplet superconducting pairing instability. We speculate that this could shed light onto a rather mysterious insulating state observed in the strongly disordered superconducting films in a broad region of magnetic fields.
