# Dynamical l-bits in Stark many-body localization

@inproceedings{Gunawardana2021DynamicalLI, title={Dynamical l-bits in Stark many-body localization}, author={Thivan Gunawardana and Berislav Buvca}, year={2021} }

Stark many-body localized (SMBL) systems have been shown both numerically and experimentally to have Bloch many-body oscillations, quantum many-body scars, and fragmentation in the large field tilt limit. Likewise, they are believed to show localization similar to disordered MBL. We explain and analytically prove all these observations by rigorously showing the existence of novel algebraic structures that are quasi-exponentially stable in time, which we call dynamical l-bits. Moreover, we show…
