Escaping many-body localization in a single eigenstate via an emergent symmetry.

Many-body localization (MBL) is a well known example of ergodicity breaking in quantum many-body systems. However, symmetries are known to strongly influence the fate of MBL physics. In this talk, I will describe how an emergent symmetry in a single eigenstate of a disordered model protects it from MBL while not preventing the rest of the states in the spectrum from many-body localizing. I will motivate how such an example calls for exploring "inverted quantum scars", namely, non-area law states embedded in a spectrum of localized states. Reference : Phys. Rev.
