Dynamical obstruction to localization in a disordered spin chain
We analyze a one-dimensional XXZ spin chain in a disordered magnetic field. As the main
probes of the system's behavior, we use the sensitivity of eigenstates to adiabatic …

Universality in the onset of quantum chaos in many-body systems
We show that the onset of quantum chaos at infinite temperature in two many-body one-
dimensional lattice models, the perturbed spin-1/2 XXZ and Anderson models, is …

Symmetry-resolved entanglement in critical non-Hermitian systems
The study of entanglement in the symmetry sectors of a theory has recently attracted a lot of
attention since it provides better understanding of some aspects of quantum many-body …

Many-body localization in a fragmented Hilbert space
We study many-body localization (MBL) in a pair-hop** model exhibiting strong
fragmentation of the Hilbert space. We show that several Krylov subspaces have both …
