Structure of the Magneto-Exciton and Optical Properties in Fractional Quantum Hall Systems

Abstract

We report calculated dependence of magneto-exciton energy spectrum upon electron-hole separation $d$ in Fractional Quantum Hall systems. We calculated the dependence of photoluminescence upon $d$, and we obtained the doublet structure observed recently. The Raman scattering spectrum around resonance is calculated: a robust resonance peak at $\nu =1/3$ around gap value is reported.
