Pattern Formation in Quantum Ferrofluids: from Supersolids to Superglasses
J. Hertkorn, J. -N. Schmidt, M. Guo +7
Pattern formation is a ubiquitous phenomenon observed in nonlinear and out-of-equilibrium systems. In equilibrium, quantum ferrofluids formed from ultracold atoms were recently sho…
Roton Excitations in an Oblate Dipolar Quantum Gas
Jan-Niklas Schmidt, Jens Hertkorn, Mingyang Guo +7
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 cha…
The Fate of the Higgs Mode in a Trapped Dipolar Supersolid
Jens Hertkorn, Fabian Böttcher, Mingyang Guo +4
We theoretically investigate the spectrum of elementary excitations of a trapped dipolar quantum gas across the BEC-supersolid phase transition. Our calculations reveal the existen…
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…
Onset of a modulational instability in trapped dipolar Bose-Einstein condensates
Igor Ferrier-Barbut, Matthias Wenzel, Matthias Schmitt +2
We explore the phase diagram of a finite-sized dysprosium dipolar Bose-Einstein condensate in a cylindrical harmonic trap. We monitor the final state after the scattering length is…
