Local Integrals of Motion for Topologically Ordered Many-Body Localized Systems
Thorsten B. Wahl, Benjamin Béri
Many-body localized (MBL) systems are often described using their local integrals of motion, which, for spin systems, are commonly assumed to be a local unitary transform of the se…

Classification of symmetry-protected topological phases in two-dimensional many body-localized systems
Joey Li, Amos Chan, Thorsten B. Wahl
We use low-depth quantum circuits, a specific type of tensor networks, to classify two-dimensional symmetry-protected topological many-body localized phases. For (anti-)unitary on-…

Approximating observables on eigenstates of large many-body localized systems
Abishek K. Kulshreshtha, Arijeet Pal, Thorsten B. Wahl +1
Eigenstates of fully many-body localized (FMBL) systems can be organized into spin algebras based on quasilocal operators called l-bits. These spin algebras define quasilocal l-bit…
