We systematically study the properties of dipolar Bose gases with two- and three-body contact interactions at finite temperature using the Hartree–Fock-Bogoliubov-Popov approximation. In uniform case, we obtain an exciting new extension of the seminal Lee-Huang-Yang corrected equation of state that...

The implementation of the latter mechanism was the basis for the experimental observation of self-bound droplets of ultra cold atoms in homo-nuclear4,5 and hetero-nuclear6 mixtures of alkali atoms, and in dipolar c ondensates7–10 that required driving the Bose-Einstein condensate (BEC) ...
radiativeinefficiencies could be reduced.Central to all these problems is the process of Auger relaxation of multiexci-tons by which pairs of excitons in a QD sequentially collide transferring a largefraction of the energy of the pair to the surviving exciton at each step whilst dissi-pating some...
Finally, the behavior of dipolar vortex droplets confined within a wake-depth annular potential is also discussed.doi:10.1016/j.chaos.2024.115762Hao HuangHongcheng WangChin Seong LimKok-Cheong WongElsevier LtdChaos, Solitons & Fractals
BINARY mixturesWe study two-dimensional (2D) isotropic quantum droplets (QDs) in dipolar binary Bose鈥揈instein condensates (BECs). The QDs are supported by the competition between the 2D form of the Lee-Huang-Yang (LHY) term and the isotropic dipole-dipole interactions (DDIs). Moreover, ...
The formation of these droplets has been recently discovered by driving the BEC into the strongly dipolar regime. Surprisingly, instead of collapsing, the system formed stable droplets. So far, no rigorous mathematical explanation has been proved. To the best of our knowledge, only experimental ...
We investigate a spin–orbit coupled Bose–Einstein condensate containing both dipolar and non-dipolar components. Combined with Rashba spin–orbit coupling, the competition between contact and dipolar interaction reveals four distinctive exotic phases: droplet lattice phase, stripe phase, oblique stripe ...
anisotropic vortex quantum dropletsCreation of stable intrinsically anisotropic self-bound states with embedded vorticity is a challenging issue.Previously,no such states in BoseEinstein condensates(BECs)or other physical settings were known.Dipolar BEC suggests a unique possibility to predict stable two ...
Stabilized by quantum fluctuations,dipolar Bose–Einstein condensates can form self-bound liquid-like droplets.However in the Bogoliubov theory,there are imaginary phonon energies in the long-wavelength limit,implying dynamical instability of this system.A similar instability appears in the Bogoliubov ...
