The low-energy Goldstone mode in a trapped dipolar supersolid
Mingyang Guo, Fabian Böttcher, Jens Hertkorn +5
A supersolid is a counter-intuitive state of matter that combines the frictionless flow of a superfluid with the crystal-like periodic density modulation of a solid. Since the firs…
Dilute dipolar quantum droplets beyond the extended Gross-Pitaevskii equation
Fabian Böttcher, Matthias Wenzel, Jan-Niklas Schmidt +8
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 st…
Transient supersolid properties in an array of dipolar quantum droplets
Fabian Böttcher, Jan-Niklas Schmidt, Matthias Wenzel +4
We study theoretically and experimentally the emergence of supersolid properties in a dipolar Bose-Einstein condensate. The theory reveals a ground state phase diagram with three d…
