Electrodynamic Signatures of Bogoliubov Fermi Surfaces in Moiré Graphene
Ke Wang, Qijin Chen, Rufus Boyack +1
Understanding the superfluid stiffness \(D_s\) is a central problem in flat-band superconductivity. It is often interpreted together with spectroscopic probes such as tunneling, si…
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.…
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…
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…
