Magnetoexciton dispersions. Magnetoexciton dispersions , calculated in the first order in Coulomb interaction (dotted lines) and with taking into account mixing between 16 low-lying magnetoexciton states (solid lines). The dispersions are calculated at 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. Dispersions of 5 lowest-lying magnetoexciton states n2 → n1 indicated near the corresponding curves, are shown.
