We study the phase separation configurations and rotational properties of a mixture of two interacting charged Bose–Einstein condensates subjected to a magnetic field trapped in disc and Corbino geometries. We calculate the ground state energies of the azimuthal and radial phase separation configurations using the Gross–Pitaevskii and Thomas–Fermi approximations. We show that the results for the experimentally relevant system parameters of both approaches are in good agreement. For both geometries, an immiscible mixture with equal intracomponent interactions favors azimuthal phase separation for all intercomponent interactions. Only an imbalance in the intracomponent interactions can result in a transition to radial phase separation, for which the transition becomes sensitive to the shape of the trap. We present phase diagrams as functions of the inter- and intracomponent interactions. While radial phase separation is widely favoured in disc geometry, the azimuthal phase separation is favoured for narrower Corbino geometries. We explore the rotational properties of spatially separated condensates subjected to magnetic fields, studying their angular momenta and velocity fields. The quantization of circulation breaks down for azimuthal phase separation. In this case, the bulk region of the condensate continues to display superfluid flow behaviour, whereas the velocity field shows a rigid body behaviour along the phase boundaries.

我们研究了两种相互作用的带电Bose-Einstein冷凝物的混合物的相分离构型和旋转特性，这些冷凝物受到陷于圆盘和Corbino几何形状的磁场的影响。我们使用Gross–Pitaevskii和Thomas–Fermi近似计算方位角和径向相分离配置的基态能量。我们表明两种方法的实验相关系统参数的结果吻合良好。对于这两种几何形状，具有相等的组分内相互作用的不混溶混合物有利于所有组分间相互作用的方位相分离。仅组分内相互作用的不平衡会导致过渡到径向相分离，为此，过渡对陷阱的形状变得敏感。我们提出相图作为组件间和组件内交互作用的函数。尽管径向相分离在圆盘几何形状中受到广泛青睐，但方位角相分离对于较窄的Corbino几何形状却受到青睐。我们研究了空间分离的冷凝液在磁场作用下的旋转特性，研究了它们的角动量和速度场。对于方位角相分离，环流的量化被打破。在这种情况下，冷凝物的大部分区域继续显示出超流体流动特性，而速度场沿相边界显示出刚体行为。我们探索了空间分离的冷凝液在磁场作用下的旋转特性，研究了它们的角动量和速度场。对于方位角相分离，环流的量化被打破。在这种情况下，冷凝物的大部分区域继续显示出超流体流动特性，而速度场沿相边界显示出刚体行为。我们研究了空间分离的冷凝液在磁场作用下的旋转特性，研究了它们的角动量和速度场。对于方位角相分离，环流的量化被打破。在这种情况下，冷凝物的大部分区域继续显示出超流体流动特性，而速度场沿相边界显示出刚体行为。
