Chiral Superconductivity Adjacent to a Wigner Crystal in Rhombohedral Graphene
Ke Wang
Can the correlations favoring electron crystallization also generate superconductivity in the neighboring metal? We investigate this possibility in rhombohedral tetralayer graphene…
A Different Perspective on Superconductivity in Crystalline Graphene: Exploiting Energetics
Ke Wang, Shicong Song, K. Levin
A central mystery of crystalline graphene is why superconductivity is so widespread yet often confined to strange slivers near boundaries between distinct isospin-ordered metals. I…
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…
