Supersolidity in Two-Dimensional Trapped Dipolar Droplet Arrays Open
We theoretically investigate the ground states and the spectrum of elementary excitations across the superfluid to droplet crystallization transition of an oblate dipolar Bose-Einstein condensate. We systematically identify regimes where s…

Roton Excitations in an Oblate Dipolar Quantum Gas Open
We observe signatures of radial and angular roton excitations around a droplet crystallization transition in dipolar Bose-Einstein condensates. In situ measurements are used to characterize the density fluctuations near this transition. Th…

Density Fluctuations across the Superfluid-Supersolid Phase Transition in a Dipolar Quantum Gas Open
Phase transitions share the universal feature of enhanced fluctuations near\nthe transition point. Here we show that density fluctuations reveal how a\nBose-Einstein condensate of dipolar atoms spontaneously breaks its translation\nsymmetr…

Transient Supersolid Properties in an Array of Dipolar Quantum Droplets Open
We study theoretically and experimentally the emergence of supersolid\nproperties in a dipolar Bose-Einstein condensate. The theory reveals a ground\nstate phase diagram with three distinct regimes - a regular Bose-Einstein\ncondensate, in…

Dilute dipolar quantum droplets beyond the extended Gross-Pitaevskii equation Open
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 drople…
