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- $T_{c}$ cuprates and other strongly correlated…

Upper bound on $T_{c}$ in a strongly coupled electron-boson superconductor

Nikolay V. Gnezdilov, Rufus Boyack

Migdal-Eliashberg theory of boson-mediated superconductivity contains a $λ$ divergence in the critical temperature $T_{c}$ for strong electron-boson coupling $λ$ . In the convent…
