Sažetak
We have studied quantum droplets in Bose-Bose mixtures using quantum Monte Carlo methods at T = 0. Using di↵erent interaction models, we determine range of validity of the universal equation of state of the symmetric liquid mixture as a function of two parameters: s-wave scattering length and the e↵ective range. It is shown that the Lee-Huang-Yang correction is sufficient only for extremely dilute liquids with the additional restriction that the range of the potential is small enough. We developed a new density functional which goes beyond the Lee-Huang-Yang term and used it to determine density profiles of self- bound drops. Relation with experiments are discussed.
