Superconductivity from Repulsive Interactions in Bernal Bilayer Graphene

Explore the intriguing phenomenon of superconductivity in Bernal-stacked bilayer graphene through this comprehensive 1-hour 18-minute lecture by Glenn Wagner from PCS Institute for Basic Science. Delve into the fascinating experimental observations of superconductivity under specific conditions, including flattened energy bands induced by electrical displacement fields. Examine the unique characteristics of this superconductor, which only manifests in non-zero magnetic fields or when spin-orbit coupling is induced by substrate interactions. Gain insights into a functional renormalization group study that offers a unified explanation for the superconducting mechanism in both scenarios. Discover the purely electronic instability of the Kohn-Luttinger type, which can be triggered by magnetic fields or Ising spin-orbit coupling, providing a natural explanation for the experimental observations. Enhance your understanding of this cutting-edge research in condensed matter physics and its implications for the field of superconductivity.
