Geometric superfluid stiffness of Kekulé superconductivity in magic-angle twisted bilayer graphene
Ke Wang, Qijin Chen, Rufus Boyack +1
Superconductivity in twisted graphene is probed by tunneling spectroscopy and superfluid stiffness, two observables that access the same order parameter from complementary perspect…
Kekulé Superconductivity in Twisted Magic Angle Bilayer Graphene
Ke Wang, K. Levin
While it has been one of the most important new physics discoveries in the last decade, the nature of superconductivity in the twisted graphene family remains an unsolved problem.…
Anomalous Superfluid Density in Pair-Density-Wave Superconductors
Ke Wang, Qijin Chen, Rufus Boyack +1
Pair-density-wave (PDW) states are a long-sought-after phase of quantum materials, with the potential to unravel the mysteries of high- cuprates and other strongly correlated…
Non-Quantum-Critical Routes to Magnetic Superconductivity
Zhiqiang Wang, Ke Wang, K. Levin
Electronic superconductivity is most commonly understood to be associated with magnetic quantum criticality. This framework is natural when a quantum critical point is present belo…
