Two-dimensional electrons in a strong magnetic field
Bychkov Yu. A., Iordanskii S. V., Eliashberg G. M.
The wave functions and spectra of complexes comprised of two or more electrons are determined for a two-dimensional case in the strong-field limit (the magnetic length is shorter than the effective Bohr radius). The electron complexes, which are localized in the charged impurity, are calculated. The spectra for the exciton and spin-wave excitations are obtained for a close-packed electron system (all the states of the lower Landau level are occupied).
