“…", were essentially concentrated around repulsive interaction between particles. The studying of stability of the conventional BEC (or gBEC) in the imperfect Bose-Gas (IBG) with a direct fast-decreasing two-body repulsive interaction is still in progress [15,16,17,18]. Whereas, if one counterbalances direct attractive interaction by a repulsion stabilising the boson system, this attraction may be the origin of a new mechanism of condensation called the non-conventional condensation.…”

The paper presents a review of results concerning the non-conventional dynamical condensation versus conventional Bose-Einstein condensation, including the case of generalised van den Berg-Lewis-Pulé condensate. The review is based on detailed discussion of two models: a simple toy model and the Bogoliubov Weakly Imperfect Bose-Gas model, which was invented for explanation of superfluity of liquid 4 He, but which is also instructive for analysis of non-conventional condensation regarding some recent interpretations of experimental data.
