    Abstract: This work reports on a theoretical investigation of a double Cd1-xZnxS quantum dot embedded in an insulating material.The quantum dots are assumed to have a flattened cylindrical geometry with a finite barrier at the boundary.The energy levels splitting has been computed, using the tight binding approximation, in the case of the heavy and light hol...

    Abstract: We discuss system with non-isotropic non-Heisenberg Hamiltonian with nearest neighbor exchange within a mean field approximation process. We derive equations describing non-Heisenberg non-isotropic model using coherent states in real parameters and then obtain dispersion equations of spin wave of dipole and quadrupole branches for a small linear ex...
