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 […

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…
