Quantum droplets can emerge in bosonic binary magnetic gases (BMGs) from the interplay of short- and long-ranged interactions, and quantum fluctuations. We develop an extended mean field theory for this system and use it to predict equilibrium and dynamical properties of BMG droplets. We present a phase diagram and characterize miscible and immiscible droplet states. We also show that a single-component self-bound droplet can bind another magnetic component, which is not in the droplet regime, due to the interspecies dipole-dipole interactions. Our results should be realizable in experiments with mixtures of highly magnetic lanthanide atoms.

二元电磁气体的量子液滴态

量子液滴可以通过短程和长程相互作用以及量子涨落的相互作用而出现在玻色二元磁性气体(BMG)中。我们为该系统开发了扩展的平均场理论,并将其用于预测BMG液滴的平衡和动力学性质。我们提供了一个相图,并描述了可混溶和不可混溶的液滴状态。我们还表明,由于种间偶极-偶极相互作用,单组分自束缚液滴可以结合另一种磁性组分,该组分不在液滴状态。我们的结果应该在高磁性镧系元素原子的混合物的实验中实现。
