By approximation of the optical conductivity spectra, a low-frequency relaxation dynamics of the Falicov-Kimball model with correlated hopping on the Bethe lattice is studied. Also, the single-magnon spectra of the one-dimensional frustrated Heisenberg spin chains are calculated, and ground state of the quantum antiferromagnetic Heisenberg model on two-layer lattices of different geometry is examined.
