Self-bound dipolar droplets and supersolids in molecular Bose-Einstein condensates
Matthias Schmidt, Lucas Lassablière, Goulven Quéméner +1
We numerically study the many-body physics of molecular Bose-Einstein condensates with strong dipole-dipole interactions. We observe the formation of self-bound droplets, and explo…
A laser cooling scheme for precision measurements using barium monofluoride (137Ba19F) molecules
Felix Kogel, Marian Rockenhäuser, Ralf Albrecht +1
We theoretically investigate the laser cooling of fermionic barium monofluoride (137BaF) molecules, which are promising candidates for precision studies of weak parity violation an…
Topological quantum critical points in the extended Bose-Hubbard model
Joana Fraxanet, Daniel González-Cuadra, Tilman Pfau +3
The combination of topology and quantum criticality can give rise to an exotic mix of counterintuitive effects. Here, we show that unexpected topological properties take place in a…
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…
Supersolidity in Two-Dimensional Trapped Dipolar Droplet Arrays
J. Hertkorn, J. -N. Schmidt, M. Guo +8
We theoretically investigate the ground states and the spectrum of elementary excitations across the superfluid to droplet crystallization transition of an oblate dipolar Bose-Eins…
