Enhanced Stability of Self-Bound Droplets in Quasi-One Dimension via Interspecies Quantum Fluctuations in Ultracold Bose–Bose Mixtures
Considering both interspecies and intraspecies quantum fluctuations in quasi-one dimensional ultracold Bose–Bose mixtures, we show that new LHY-like effects lead to generalized stability conditions against collapse and phase separation. Moreover, we demonstrate that the stability of self-bound droplets is enhanced by interspecies correlations. The contribution to the energy of the quadratic fluctuations is shown to have negligible effects in the Bogoliubov approximation.
