    • The polarization so defined is not to be confused with a dipole moment. For the situations we consider here, the ground state of the cell has no dipole moment, though it may have a quadrupole moment. The cell polarization simply measures the degree to which the electronic charge is aligned and the direction of that alignment

    • For the standard cell, we take [formula omitted] to be the Coulomb energy of two electrons separated by one-third the dot diameter D, a physically reasonable first approximation

    • Reference 6 examines the behavior of lines of cells as all these Hamiltonian parameters are varied. The bistable behavior we examine here is not critically dependent on a particular choice of these parameters, but holds for a wide range of parameter choices

    • Enlarging the quantum dots lowers the onsite energy [formula omitted] and makes it energetically more favorable to occupy the larger dots.
