- Abstract summary: Competing short- and long-range interactions represent distinguished ingredients for the formation of complex quantum many-body phases.
We leverage the van der Waals and dipole-dipole interactions of the Rydberg atoms to obtain the zero-temperature phase diagram for a uniform chain and a dimer model.
This demonstrates the versatility of the Rydberg platform in studying physics involving short- and long-ranged interactions simultaneously.

- Abstract: Competing short- and long-range interactions represent distinguished
ingredients for the formation of complex quantum many-body phases. Their study
is hard to realize with conventional quantum simulators. In this regard,
Rydberg atoms provide an exception as their excited manifold of states have
both density-density and exchange interactions whose strength and range can
vary considerably. Focusing on one-dimensional systems, we leverage the van der
Waals and dipole-dipole interactions of the Rydberg atoms to obtain the
zero-temperature phase diagram for a uniform chain and a dimer model. For the
uniform chain, we can influence the boundaries between ordered phases and a
Luttinger liquid phase. For the dimerized case, a new type of
bond-order-density-wave phase is identified. This demonstrates the versatility
of the Rydberg platform in studying physics involving short- and long-ranged
interactions simultaneously.
