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…
Dynamics generated by spatially growing derivations on quasi-local algebras
Stefan Teufel, Marius Wesle, Tom Wessel
We prove global existence and uniqueness of dynamics on the quasi-local algebra of a quantum lattice system for spatially growing derivations $\mathcal{L}_Φ= \sum_x…
From decay of correlations to locality and stability of the Gibbs state
Ãngela 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…
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…
