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…
