Experimental probes of Stark many-body localization

Many-body localization (MBL), a transportless phase in disordered interacting quantum systems, has recently been observed in systems without disorder but instead with a strong linear potential, a phenomenon known as Stark MBL. Here, the authors show how several experimental setups devised to study conventional MBL can also be used for Stark MBL, due to their almost identical phenomenologies. They then discuss Stark MBL as a possible experimental setting to explore Hilbert space fragmentation in systems with conserved dipole moment.
