Renormalized Harmonic-Oscillator Description of Confined Electron Systems with Inverse-Square Interaction
N. Kawakami
Abstract
An integrable model for SU(ν) electrons with inverse-square interaction is studied for the system with confining harmonic potential. We develop a new description of the spectrum based on the renormalized harmonic-oscillators which incorporate interaction effects via the repulsion of energy levels. This approach enables a systematic treatment of the excitation spectrum as well as the ground-state quantities.
