Computing the spectrum and pseudospectrum of infinite-volume operators from local patches
Paul Hege, Massimo Moscolari, Stefan Teufel
We show how the spectrum of normal discrete short-range infinite-volume operators can be approximated with two-sided error control using only data from finite-sized local patches.…

Finding spectral gaps in quasicrystals
Paul Hege, Massimo Moscolari, Stefan Teufel
We present an algorithm for reliably and systematically proving the existence of spectral gaps in Hamiltonians with quasicrystalline order, based on numerical calculations on finit…
