| 1 | Two—Electron Energy Spectrum in a Parabolic Quantum Dot Under a Magnetic Field显示文摘Two interacting electrons in a harmonic oscillator potential under the influence of a perpendicular homo-geneous magnetic field are considered. The energies of two-electron quantum dots with the electron-LO-phonon couplingas a function of magnetic field are calculated. Calculations are made by using the method of few-body physics withinthe effective-mass approximation. Our results show that the electron-LO-phonon coupling effect is very important insemiconductor quantum dots. | XIEWen-Fang | 2003 | Communications in Theoretical Physics2003，39，4： | 4 |
| 2 | Off—Center D—Centers in a Quantum Dot in the Presence of a Perpendicular Magnetic Fields显示文摘We investigate the effect of the position of the donor in quantum dots on the energy spectrum in the presence ofa perpendicular magnetic field by using the method of few-body physics. As a function of the magnetic field, we find, when D- centers are placed sufficiently off-center, discontinuous ground-state transitions which are similar to those found in many-electron parabolic quantum dots. Series of magic numbers of angular momentum which minimize the ground-state electron-electron interaction energy have been discovered. The dependence of the binding energy of the ground-state of the 1D- center on the dot radius for a few values of the magnetic field strength is obtained and compared with other results. | XIEWen-Fang | 2001 | Communications in Theoretical Physics2001，35，4： | 1 |
| 3 | Four—Electron Systems in a Coupled Double—Layer Quantum Dots显示文摘Making use of the method of few-body physics, the energy spectrum of a four-electron system consisting in a vertically coupled double-layer quantum dot as a function of the strength ofa magnetic field is investigated. Discontinuous ground-state transitions induced by an external magnetic field are shown. We find that, in the strong coupling case, the ground-state transitions depend not only on the external magnetic field B but also on the distance d between double-layer quantum dots. However, in the case of weak coupling, the ground-state transitions occur in the new sequence of the values of the magic angular momentum. Hence, the interlayer separation d and electron-electron interaction strongly affect the ground state of the coupled quantum dots. | XIEWe-Fang | 2003 | Communications in Theoretical Physics2003，39，3： | 1 |
| 4 | Low—Lying States of the A^+B^—A^+B^— Coulomb systems in Two—Dimensional Quantum Dots显示文摘The features of the low-lying spectra of four-body A+B-A+B- systems have been deduced based on symmetry. Using the method of few-body physics, we calculate the energy spectra of A + B- A + B- systems in a harmonic quantum dot. We find that the biexciton in a two-dimensional quantum dot may have other bound excited states and the quantum mechanical symmetry plays a crucialrole in determining the energy levels and structures of the low-lying states. | XIEWen-Fang | 2001 | Communications in Theoretical Physics2001，35，3： | 0 |
