The properties of the ground state and the spectrum of elementary excitations of an ultracold rarefied three-dimensional Bose gas of particles with arbitrary nonzero spin are investigated. It is assumed that the bare interaction consists of two parts

It is shown that the homogeneous state of the spatially separated electrons and holes in coupled quantum wells (CQW) is instable if the layer charge density is smaller than the critical value $$n_{c}$$ specified by the parameters of the CQW. The effe

A many-component electron–hole plasma is considered in coupled quantum wells. The electrons and the holes are localized in the different wells. It is found in our previous works that the electron–hole liquid is the ground state of the system. In

The many-body correlation effects in the spatially separated electron and hole layers in the coupled quantum wells are investigated. A special case of the many-component electron–hole system is considered. It is shown that if the hole mass is much

It has been shown that many-body Coulomb correlations in double quantum wells with spatially separated electrons and holes result in the formation of a degenerate electron-hole liquid where an average distance between the particles is smaller than th

Many-component electron-hole plasma is considered in the coupled quantum wells. The electrons are assumed to be localized in one quantum well (QW) while the holes are localized in the other QW. It is found that the homogeneous charge distribution wit

The influence of multiparticle correlation effects and Cooper pairing in an ultracold Fermi gas with a negative scattering length on the formation rate of molecules is investigated. Cooper pairing is shown to cause the formation rate of molecules to
