Rydberg platform for non-ergodic chiral quantum dynamics
arxiv(2023)
摘要
We propose a mechanism for engineering chiral interactions in Rydberg atoms
via a directional antiblockade condition, where an atom can change its state
only if an atom to its right (or left) is excited. The scalability of our
scheme enables us to explore the many-body dynamics of kinetically constrained
models with unidirectional character. We observe non-ergodic behavior via
either scars, confinement, or localization, upon simply tuning the strength of
two driving fields acting on the atoms. We discuss how our mechanism persists
in the presence of classical noise and how the degree of chirality in the
interactions can be tuned, opening towards the frontier of directional,
strongly correlated, quantum mechanics using neutral atoms arrays.
