Query: New exact analytical results for two quasiparticle excitation in the
  fractional quantum Hall effect   In this work, two quasiparticle excitation energies per particle are
calculated analytically for systems with up to $N = 7$ electrons in both
Laughlin and composite fermions (CF) theories by considering the full jellium
potential which consists of three parts, the electron-electron,
electron-background, and background-background Coulomb interactions. The exact
results we have obtained confirm the fact that the CF-wavefunction for two
quasiparticles has lower energy than Laughlin wavefunction though the found
difference between Laughlin and (CF) two quasiparticle energies decreases as
the system size increases.
