Дослiдження бозонного спектра двовимiрних оптичних ґраток зi структурою типу графену. Надплинна фаза
The energy spectrum of a system of Bose atoms in the superfluid phase in an optical lattice of the graphene type has been studied. The dispersion laws for the energy bands and the single particle spectral densities are calculated in the random phase approximation and in the framework of the hard-cor...
