imaging of Rydberg atoms in a Mott insulator reveals the emergence of spatially ordered excitation patterns with random orientation but well-defined geometry.
Ordered structures in quantum matter
The realization of long-range interactions in ultracold atomic gases would open up a new realm of many-body physics. Rydberg atoms are highly suited to this goal because of their strong van der Waals forces. This experiment reports high resolution,
in situ
imaging of Rydberg atoms and direct measurement of their strong correlations. The observations reveal the emergence of spatially ordered excitation patterns with random orientation but well-defined geometry. This work demonstrates the potential of Rydberg gases to realize exotic phases of matter, thereby laying the basis for quantum simulations of long-range interacting quantum magnets.
The ability to control and tune interactions in ultracold atomic gases has paved the way for the realization of new phases of matter. So far, experiments have achieved a high degree of control over short-range interactions, but the realization of long-range interactions has become a central focus of research because it would open up a new realm of many-body physics. Rydberg atoms are highly suited to this goal because the van der Waals forces between them are many orders of magnitude larger than those between ground-state atoms
