DOI: 10.1103/physrevb.100.184312
Abstract: We study the eigenstate properties of a nonintegrable spin chain that was recently realized experimentally in a Rydberg-atom quantum simulator. In the experiment, long-lived coherent many-body oscillations were observed only when the system was initialized… read more here.

DOI: 10.1103/physrevb.110.144302
Abstract: Unstable periodic orbits (UPOs) play a key role in the theory of chaos, constituting the"skeleton"of classical chaotic systems and"scarring"the eigenstates of the corresponding quantum system. Recently, nonthermal many-body eigenstates embedded in an otherwise thermal spectrum… read more here.
