Low-density parity-check codes as stable phases of quantum matter
Phases of matter with robust ground-state degeneracy, such as the quantum toric code, are
known to be capable of robust quantum information storage. Here, we address the converse …

Response theory for locally gapped systems
J Henheik, T Wessel - arxiv preprint arxiv:2410.10809, 2024 - arxiv.org
We introduce a notion of a\emph {local gap} for interacting many-body quantum lattice
systems and prove the validity of response theory and Kubo's formula for localized …

Towards absolutely stable ergodicity breaking in two and three dimensions
We propose new physically reasonable systems capable of avoiding ergodicity at infinite
time in the thermodynamic limit, even with generic perturbations and when coupled to a heat …
