Magnetoplasmon dispersions. Magnetoplasmon energies Ω n 1 n 2 , calculated in the lowest Landau level approximation (solid lines), with taking into account mixing between 2 (short dash lines) and 3 (long dash lines) Landau levels of electron and hole, and with taking into account mixing between all Landau levels (dotted lines). 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. Dispersions of 3 lowest-lying magnetoplasmon modes n2n1, indicated near the corresponding curves, are shown.
