Universal Theory of Incoherent Metals
Aaron Kleger, Nikolay Gnezdilov, Rufus Boyack
Numerous unconventional superconductors such as cuprates, heavy-fermions, and twisted-bilayer graphene exhibit incoherent metallic transport above the superconducting critical temp…
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…
Physical constraints on effective non-Hermitian systems
Aaron Kleger, Rufus Boyack
Interacting and open quantum systems can be formulated in terms of an effective non-Hermitian Hamiltonian (NHH), however, there are important constraints that must be satisfied by…
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…
Upper bound on in a strongly coupled electron-boson superconductor
Nikolay V. Gnezdilov, Rufus Boyack
Migdal-Eliashberg theory of boson-mediated superconductivity contains a divergence in the critical temperature for strong electron-boson coupling . In the convent…
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…
