quantum scars of bosons with correlated hopping

Quantum many-body scarring, a peculiar phenomenon whereby a system thermalizes whilst it keeps returning to its initial state during the time evolution, has recently been observed in experiments on arrays of Rydberg atoms. The authors theoretically investigate the spectral properties of three Hamiltonians using a chain of bosons with density-dependent hopping, providing new insight in the phenomenon of many-body quantum scarring.
