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…
New states of matter with fine-tuned interactions: quantum droplets and dipolar supersolids
Fabian Böttcher, Jan-Niklas Schmidt, Jens Hertkorn +5
Quantum fluctuations can stabilize Bose-Einstein condensates (BEC) against the mean-field collapse. Stabilization of the condensate has been observed in quantum degenerate Bose-Bos…
Stable spin domains in a non-degenerate ultra-cold gas
S. D. Graham, D. Niroomand, R. J. Ragan +1
We study the stability of two-domain spin structures in an ultra-cold gas of magnetically trapped Rb atoms above quantum degeneracy. Adding a small effective magnetic field…
Retardation effects in induced atomic dipole-dipole interactions
S. D. Graham, J. M. McGuirk
We present mean-field calculations of azimuthally averaged retarded dipole-dipole interactions in a Bose-Einstein condensate induced by a laser, at both long and short wavelengths.…
Longitudinal spin diffusion in a nondegenerate trapped Rb gas
D. Niroomand, S. D. Graham, J. M. McGuirk
Longitudinal spin diffusion of two pseudo-spin domains is studied in a trapped Rb sample above quantum degeneracy, and the effect of coherence in the domain wall on the dyna…
