Magnetoexciton energies with Landau level mixing. Magnetoexciton energies at rest , calculated with taking into account N electron and N hole Landau levels, with stepwise increasing N (crosses). The fits to these energies with inverse-square-root function (solid lines) and limiting values of at N → ∞ (dotted lines) are also shown. The results are presented for different filling factors ν and different rs: (a) ν = 0, rs = 0.5, (b) ν = 0, rs = 1, (c) ν = 0, rs = 2, (d) ν = 1, rs = 0.5, (e) ν = 1, rs = 1, (f) ν = 1, rs = 2.
