Dipolar quantum droplets are exotic quantum objects that are self-bound due to the subtle balance of attraction, repulsion and quantum correlations. Here we present a systematic study of the critical atom number of these self-bound droplets, comparing the experimental results with extended mean-feld Gross-Pitaevskii equation (eGPE) and quantum Monte-Carlo simulations of the dilute system. The respective theoretical predictions differ and we show that the experiment supports the quantum Monte…

Self-Bound Doubly Dipolar Bose-Einstein Condensates.

By varying the angle between the two dipoles, a dimensional crossover from quasi-one-dimensional to quasi-two-dimensional self-bound droplets is found, which opens a so far unique scenario in condensate physics, in which adimensional crossover is solely driven by interactions in the absence of any confinement.

By adding a repulsive two-body potential, this work finds a narrow window of interaction parameters leading to stable ground-state configurations of droplets in a crystalline arrangement without resorting to additional stabilizing mechanisms or specific three-body forces.

Observation of Quantum Droplets in a Strongly Dipolar Bose Gas.

By systematic measurements on individual droplets it is demonstrated quantitatively that quantum fluctuations mechanically stabilize them against the mean-field collapse, and the interference of several droplets indicating that this stable many-body state is phase coherent.

In a combined experimental and theoretical analysis, this work determines the parameter regime for the formation of coherent stripes, whose lifetime of a few tens of milliseconds is limited by the eventual destruction of the stripe pattern due to three-body losses.

Scissors Mode of Dipolar Quantum Droplets of Dysprosium Atoms.

The results establish an analogy between quantum droplets and atomic nuclei, where the existence of the scissors mode is also only due to internal interactions, and open the possibility to explore physics beyond the available theoretical models for strongly dipolar quantum gases.
