Unconventional multi-band superconductivity at two-dimensional oxide interfaces

A presence of two-dimensional superconductivity at the interface between LaAlO3 and SrTiO3, together with strong Rashba spin-orbit coupling, is of particular interest as theory predicts unconventional superconducting pairing and topological superconductivity. Using, resonant microwave experiment to extract the phase rigidity and the gap energy of the superconductor, and upper critical magnetic field, we demonstrate that multi-condensate superconductivity can occur at the interface as theoretically predicted.
