Investigation of the bosonic spectrum of two-dimensional optical graphene-type lattices. Superfluid phase
I. V. Stasyuk, O. V. Velychko, I. R. Dulepa
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…

Investigation of the bosonic spectrum of two-dimensional optical graphene-type lattices. Normal phase
I. V. Stasyuk, I. R. Dulepa, O. V. Velychko
The band spectrum of bosonic atoms in two-dimensional honeycomb optical lattices with the graphene-type structure has been studied. The dispersion laws in the bands and the one-par…
