  • Abstract
    We study the dynamics of excitons in GaAs quantum wells via optical-pump/terahertz-probe spectroscopy in magnetic fields. We found that the 1s-2p, intra-excitonic transition is robust at high magnetic fields even under high excitation fluences, indicating magnetically enhanced stability of excitons.
