Abstract

Considering both interspecies and intraspecies fluctuations in ultracold bose-bose mixtures, we derive generalized stability conditions against collapse and phase separation. Furthermore, by examining the energy density of the system, we show that new LHY-like effects may enforce or destroy the stability according to the excitation branch, therefore, permitting or prohibiting the existence of droplet states.
