Popis:	By employing the method of the multiconfigurational time-dependent Hartree for bosons, we investigate the ground state properties of a singly trapped dipolar gas of spinless bosons. We show that the repulsive interactions favor the formation of the fragmented ground state. In particular, we find the formation of the fragmented state is mainly due to the interaction energies associated with the one- and two-particle exchanges between orbitals. We also obtain the stability diagram of the system and find that the stability of the system is significantly enhanced by the appearance of the fragmentation.
