Universal aspects of bulk density of states in non-Hermitian lattices
Mykhailo Pavliuk, Askar Iliasov, Emil J. Bergholtz +1
Non-Hermitian lattice Hamiltonians generally exhibit strong boundary sensitivity, with periodic and open boundary conditions producing distinct density of states (DOS) in the compl…

Superconductivity in hyperbolic spaces: Cayley trees, hyperbolic continuum, and BCS theory
Mykhailo Pavliuk, Tomáš Bzdušek, Askar Iliasov
We investigate -wave superconductivity in negatively curved geometries, focusing on Cayley trees and the hyperbolic plane. Using a self-consistent Bogoliubov-de Gennes approach…
