Opis:: The interaction of spins localized within the band-inverted heterojunction with the Weyl excitations is shown to differ significantly from the usual s-d interaction. The indirect exchange interaction is long-range and anti-ferromagnetic. The magnitude of interaction decreases with the distance as R$\text{}^{-3}$. The effective interaction depends on the parameters of electron energy spectrum and parameters of the heterojunction as well. It consists of anisotropic Heisenberg term and of pseudodipole terms.

Opis:: The energy spectrum of a quantum dot made from IV-VI narrow gap semiconductors is studied. The calculations of the energy levels as functions of the dot radius are performed. When the anisotropy of the bare energy spectrum is strong, the energy levels are calculated using Fal'kovskii's adiabatic approximation for multiband systems. When the quantum dot material has an inverted band gap with respect to the host, the low-energy states within the fundamental gap are shown to arise.
