Non-perturbatively slow spread of quantum correlations in non-resonant systems
Ben T. McDonough, Marius Lemm, Andrew Lucas
Strong disorder often has drastic consequences for quantum dynamics. This is best illustrated by the phenomenon of Anderson localization in non-interacting systems, where destructi…
Two classes of quantum spin systems that are gapped on any bounded-degree graph
Nicholas Hunter-Jones, Marius Lemm
We study translation-invariant quantum spin Hamiltonians on general graphs with non-commuting interactions either given by (i) a random rank- projection or (ii) Haar projectors.…
Uniform-in-temperature locality estimates for weakly interacting quantum systems
Arka Adhikari, Joscha Henheik, Marius Lemm +1
The locality of thermal quantum states has emerged as a key input for applications to thermalization, response theory, and efficient simulability. Locality is either captured by th…
Dynamics and equilibrium states of infinite systems of lattice bosons
Andreas Deuchert, Jonas Lampart, Marius Lemm
We consider the dynamics of systems of lattice bosons with infinitely many degrees of freedom. We show that their dynamics defines a group of automorphisms on a --algebra intr…
