Novel explicit solutions of two-component Bose gases slightly in touch with a reservoir of cold atoms, with time-dependent two- and three-body interactions and under the influence of linear fields are constructed. Using a relatively simple method, complexes made of “solitons-generalized Jacobi elliptic functions”, “solitons-triangular periodic” waves, and others, are unveiled. The mean dynamics, relative phase, the miscibility-immiscibility transition are fully controlled by the geometry of linear fields and the mass ration of the atomic species. Our analytical predictions are confirmed by intensive numerical simulations with a good accuracy.
