Challenges to observation of many-body localization
We study time dynamics of 1D disordered Heisenberg spin-1/2 chains focusing on a regime

Critical properties of the Anderson transition on random graphs: Two-parameter scaling theory, Kosterlitz-Thouless type flow, and many-body localization
The Anderson transition in random graphs has raised great interest, partly out of the hope
that its analogy with the many-body localization (MBL) transition might lead to a better …
