Spectral weights of doublon in interacting Hofstadter model

Strongly Correlated Electrons 2018-08-31 v1

Abstract

In this article, two-particle Greens functions are computed for different strengths of interactions for particles in Hofstadter lattices, providing informations on spectral weights of doublons. The calculations are performed for a finite lattice without disorder. The splitting in spectra under the effect of external magnetic field for non-interacting and interacting pairs are compared.
