论文摘要
二进制玻色 - 因斯坦冷凝水混合物中的量子液滴的存在依赖于卑鄙的场效应，并与平均场效应竞争。有趣的是，均值的野外效应正在从3D中的排斥性变为1D的吸引力，导致行为截然不同。我们详细研究了径向波函数被冷冻的准-1D制度中的这两个策略之间的交叉。对于所有值和平均场相互作用的符号都存在量子液滴。我们发现，接近交叉的人在实验上具有吸引力，因为它降低了三体损失的相对重要性，并为交叉中量子液滴的实现提供了逼真的数字，这将允许测试超出势场理论的前所未有的精确性。
The existence of quantum droplets in binary Bose-Einstein condensate mixtures rely on beyondmean field effects, competing with mean-field effects. Interestingly, the beyond-mean field effect is changing from repulsive in 3D to attractive in 1D leading to drastically different behaviors. We study in detail the crossover between these two regimes in a quasi-1D regime where the radial wavefunction is frozen. Quantum droplets exist for all values and sign of the mean-field interaction. We find that approaching the crossover is experimentally appealing as it reduces the relative importance of three-body losses and give realistic numbers for the realization of quantum droplet in the crossover, which would permit to test beyond-mean-field theories to an unprecedented precision.
