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…
Stable multipole solitons in defocusing saturable media with an annular trapping potential
Xiaoli Lang, Boris A. Malomed, Liangwei Dong
We systematically investigate the existence, stability, and propagation dynamics of multipole-mode (necklace-shaped) solitons in the two-dimensional model of an optical medium with…
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…
