摘要： 精确对角化技术用于研究在二维谐波势中相互作用电子的多粒子性质。 单粒子基态仅限于最低的朗道能级。 结果作为系统总角动量的函数进行分析。 只有在对应填充因子 1, 1/3, 1/5 等的角动量处，系统才完全极化。 最低能量态表现出自旋波、畴和局域化，这取决于角动量。 涡旋仅存在于激发的极化状态中。 高角动量极限下显示电子的局域化以及电荷和自旋激发的分离。 显示英文摘要

摘要： The exact diagonalization technique is used to study many-particle properties of interacting electrons with spin, confined in a two-dimensional harmonic potential. The single-particle basis is limited to the lowest Landau level. The results are analyzed as a function of the total angular momentum of the system. Only at angular momenta corresponding to the filling factors 1, 1/3, 1/5 etc. the system is fully polarized. The lowest energy states exhibit spin-waves, domains, and localization, depending on the angular momentum. Vortices exist only at excited polarized states. The high angular momentum limit shows localization of electrons and separation of the charge and spin excitations.
