We study the formation of bright solitons in the impurity component ofBose-Einstein condensate (BEC)-impurity mixture by using the time-dependentHartree-Fock-Bogoliubov theory. While we assume the boson-boson andimpurity-boson interactions to be effectively repulsive, their character can bechanged spontaneously from repulsive to attractive in the presence of stronganomalous correlations. In such a regime the impurity component becomes asystem of effectively attractive atoms leading automatically to the generationof bright solitons. We find that this soliton decays at higher temperatures dueto the dissipation induced by the impurity-host and host-host interactions. Weshow that after a sudden increase of the impurity-boson strength a train ofbright solitons is produced and this can be interpreted in terms of themodulational instability (MI) of the time-dependent impurity wave function.
