论文摘要
我们使用精确的量子蒙特卡洛技术来研究在两个空间维度中与接触相互作用的两个组件的波体混合物中量子液滴的性质。我们系统地研究表面张力，密度曲线和呼吸模式与液滴中颗粒数的函数以及种类内抑制和种间吸引力之间的耦合强度之比。我们发现，在大多数感兴趣的情况下，偏离广义GROSS-PITAEVSKII方程的预测很小。
We use exact Quantum Monte Carlo techniques to study the properties of quantum droplets in two-component bosonic mixtures with contact interactions in one spatial dimension. We systematically study the surface tension, the density profile and the breathing mode as a function of the number of particles in the droplet and of the ratio of coupling strengths between intra-species repulsion and inter-species attraction. We find that deviations from the predictions of the generalized Gross-Pitaevskii equation are small in most cases of interest.
