Robust quantum-droplet necklace clusters in three dimensions
Liangwei Dong, Dongshuai Liu, Boris A. Malomed
We report the existence of quasi-stable ring-shaped (necklace-shaped) clusters built, in the free space, of 3D quantum droplets (QDs) in a binary Bose-Einstein condensate, modeled…
Hopfions in the Lee-Huang-Yang superfluids
Liangwei Dong, Mingjing Fan, Boris A. Malomed +1
It is known that, under appropriate conditions, mean-field interactions can be canceled in binary BEC, leading to the formation of the Lee-Huang-Yang (LHY) superfluid, in which the…
Stable higher-order vortex quantum droplets in an annular potential
Liangwei Dong, Mingjing Fan, Boris A. Malomed
We address the existence, stability, and evolution of two-dimensional vortex quantum droplets (VQDs) in binary Bose-Einstein condensates trapped in a ring-shaped potential. The int…
