论文摘要
已知排斥的玻色果混合物将其混合或分离为纯成分。在这里，我们预测了一种混合泡沫状态，其中混合相的气泡与其中一个组件的纯相共存。这是一种超级场效应，是针对不平等质量或不平等内偶联常数发生的，是由于平均场项之间的竞争，密度二次和非二次的超越均值均矫正。我们在各个维度中发现混合泡沫状态的参数，并讨论对当前实验的影响。
Repulsive Bose-Bose mixtures are known to either mix or phase-separate into pure components. Here we predict a mixed-bubble regime in which bubbles of the mixed phase coexist with a pure phase of one of the components. This is a beyond-mean-field effect which occurs for unequal masses or unequal intraspecies coupling constants and is due to a competition between the mean-field term, quadratic in densities, and a nonquadratic beyond-mean-field correction. We find parameters of the mixed-bubble regime in all dimensions and discuss implications for current experiments.
