ICMAB seminar "Unconventional multi-band superconductivity at two-dimensional oxide interfaces" by Gyanendra Singh
Unconventional multi-band superconductivity at two-dimensional oxide interfaces
by Gyanendra Singh, Department of Microtechnology and Nanoscience MC2, Chalmers University of Technology, Gothenburg, Sweden.

Abstract:
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.

Bio:
Ph.D. from the Indian Institute of Technology Kanpur India in superconducting-ferromagnetic thin-film heterostructures. Postdoctoral researcher at ESPCI Paris, France, in the group of Prof. Jerome Lesueur, and since 2018, postdoctoral researcher at Chalmers University of Technology Gothenburg, Sweden, in the QuantERA project.

Hosted by Gervasi Herranz, ICMAB researcher at the MULFOX group
