摘要: We present the adequate circular representation of charge density excitations in Quantum Hall droplets at filling factor 1. A novel set operators describes magnetoexcitons with well defined both total and center-of-mass angular momentum. The accuracy this description is shown by high overlap exact eigenstates a quantum dot magnetic field obtained from numerical calculations up to 20 electrons. From such we get good understanding energies spectral functions.
