Diagnostics of nonergodic extended states and many body localization proximity effect through real-space and Fock-space excitations

Nilanjan Roy, Jagannath Sutradhar, Sumilan Banerjee

We provide real-space and Fock-space (FS) characterizations of ergodic, nonergodic extended (NEE) and many-body localized (MBL) phases in an interacting quasiperiodic system, namel…
