Simulation of Electronic Ground Energy and Chemical Potential of Box Quantum Dot

根据密度泛函理论，用自洽迭代和变分法求解有电场和磁场下的三维盒形量子点中电子（N=1-12）的薛定谔方程，对绝对零度情况下处于基态的电子的总能量和化学势进行了数值计算，并讨论了电场和磁场对量子点中电子基态能量的影响，得出了盒形量子点中多电子系统的一些基态性质．

Using density-functional theory, the Schroedinger equation of a 3D box quantum dot in an electric field and a magnetic field has been solved self-consistently and variationally. The ground energy and the chemical potential have been computed in the limit of zero temperature. The author the influence of an electric field and a magnetic field on the ground energy of the box quantum dot.
