Effects Beyond Center-of-Mass Separability in a Trapped Bosonic Mixture: Exact Results
arXiv:2112.03098 · doi:10.1088/1742-6596/2249/1/012011
Abstract
An exactly solvable model mimicking demixing of two Bose-Einstein condensates at the many-body level of theory is devised. Various properties are expressed in closed form along the demixing pathway and investigated. The connection between the center-of-mass coordinate and in particular the relative center-of-mass coordinate and demixing is explained. The model is also exactly solvable at the mean-field level of theory, allowing thereby comparison between many-body and mean-field properties. Applications are briefly discussed.
