Abstract

Terahertz-induced intra-exciton transitions are studied in semiconductor quantum-well systems under the influence of a constant magnetic field. A systematic description is developed to include carrier-carrier interactions, terahertz transitions, and magnetic-field effects to the exciton-correlation dynamics. When a magnetic field is present, the exciton states and energies are changed directly and parametrically via the center-of-mass momentum of excitons. The numerical results show that both effects influence the terahertz spectroscopy. Especially, the transition between 1s- and 2p-exciton states is shown to depend strongly on both magnetic field and center-of-mass momentum.
