The evolutions of the von Neumann entropies of the low-lying states in two vertically coupled identical single-electron quantum dot systems with increasing magnetic field and inter-dot separation have been investigated. We show that both the external magnetic field and the inter-dot separation can induce the transition of the entropy of the system. Additionally, a suspicion (that is, the higher the excitation, the larger entropy) has been clarified and proven to be incorrect.

Exact Diagonalization Method

We present a theoretical study to investigate the effect of donor impurity on the magnetization (M) and the magnetic susceptibility [Formula: see text] of single electron quantum dot (QD) with Gaussian confinement in the presence of a magnetic field. We solve the Hamiltonian of this system, including the spin, by using the exact diagonalization method. The ground state binding energy (BE) of an electron has been shown as a function of QD radius and confinement potential depth. The behaviors of the magnetization and the magnetic susceptibility of a QD have been studied as a function of temperature, confinement potential depth, quantum radius and magnetic field. We have shown the effect of donor impurity on the magnetization and magnetic susceptibility curves of Gaussian quantum dot (GQD).
