The ground state energies of two interacting electrons confined in a coupled double quantum dot (DQD) presented in a magnetic field has been calculated by solving the relative Hamiltonian using variational and exact diagonalization methods. The singlet-triplet transitions in the angular momentum and spin of the quantum dot ground state had been shown .We have […]
In the present work, the exact diagonalization method had been implemented to calculate the ground state energy of shallow donor impurity located at finite distance along the growth axis in GaAs/AlGaAs heterostructure in the presence of a magnetic field taken to be along z direction. The impurity binding energy of the ground state had been […]
In this paper, the buckling behavior and nonlinear vibrations of graphene nanosheets in the magnetic field are studied analytically. By considering mechanical and magnetic interactions, new relationships have been proposed for the forces exerted by the magnetic field. The nonlinear governing equation is derived using Kirchhoff’s thin plate theory in conjunction with the nonlocal strain […]
