Miscibility Regimes in a 23Na–39K Quantum Mixture

The effects of miscibility in interacting two-component classical fluids are relevant a broad range daily applications. When considering quantum systems, Bose–Einstein condensates provide well-controlled platform where the miscible–immiscible phase transition can be completely characterized. In homogeneous this is governed only by competition between intra- and inter-species interactions. However, more conventional experiments dealing with trapped gases, pressure confinement increases role kinetic energy makes system miscible. most general case, diagram unbalanced mixtures different atomic species strongly modified atom number ratio gravitational sags. Here, we numerically investigate ground-state 23Na–39K mixture for interaction strengths ratios realistic experimental parameters. Defining spatial overlap resulting clouds, construct which could directly measured real experiments.
