Lieb-Robinson bounds, automorphic equivalence and LPPL for long-range interacting fermions
Stefan Teufel, Tom Wessel
We prove a Lieb-Robinson bound for lattice fermion models with polynomially decaying interactions, which can be used to show the locality of the quasi-local inverse Liouvillian. Th…
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.…
Equality of magnetization and edge current for interacting lattice fermions at positive temperature
Jonas Lampart, Massimo Moscolari, Stefan Teufel +1
We prove that the magnetization is equal to the edge current in the thermodynamic limit for a large class of models of lattice fermions with finite-range interactions satisfying lo…
From decay of correlations to locality and stability of the Gibbs state
Ángela Capel, Massimo Moscolari, Stefan Teufel +1
We show that whenever the Gibbs state of a quantum spin system satisfies decay of correlations, then it is stable, in the sense that local perturbations affect the Gibbs state only…
