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…
Quench induced collective excitations: from breathing to acoustic modes
Shicong Song, Ke Wang, Zhengli Wu +3
In trapped Bose-Einstein condensates, interaction quenches which are abrupt changes of the interaction strength typically implemented via Feshbach tuning, are a practical and widel…
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…
Tunable Molecular Interactions Near an Atomic Feshbach Resonance: Stability and Collapse of a Molecular Bose-Einstein Condensate
Zhiqiang Wang, Ke Wang, Zhendong Zhang +3
Understanding and controlling interactions of ultracold molecules is a cornerstone of quantum chemistry. While the laboratory creation of degenerate molecular gases comprised of bo…
The Higgs-Amplitude mode in the optical conductivity in the presence of a supercurrent: Gauge-invariant formulation with disorder
Ke Wang, Rufus Boyack, K. Levin
Observing the ``Higgs" or amplitude mode in superconductors has been a central challenge in condensed matter physics. Moreover, arriving at a theoretical understanding of this mode…
Universal coherent atom-molecule oscillations in the dynamics of the unitary Bose gas near a narrow Feshbach resonance
Ke Wang, Zhendong Zhang, Shu Nagata +2
Quench experiments on a unitary Bose gas around a broad Feshbach resonance have led to the discovery of universal dynamics. This universality is manifested in the measured atomic m…
Stability and Dynamics of Atom-Molecule Superfluids Near a Narrow Feshbach Resonance
Zhiqiang Wang, Ke Wang, Zhendong Zhang +3
The recent observations of a stable molecular condensate emerging from a condensate of bosonic atoms and related "super-chemical" dynamics have raised an intriguing set of question…
Bosonic thermoelectric transport and breakdown of universality
A. Rancon, Cheng Chin, K. Levin
In this paper we compare Bose transport in normal phase atomic gases with its counterpart in Fermi gases, illustrating the non-universality of two dimensional bosonic transport ass…
