Abstract: In this thesis, the candidate studies the effects of externally applied fields on spin and charge transport in two dimensional systems strongly coupled to light. On one hand, the influence of a strong monochromatic laser field on charge conductivity and spin relaxation in a two dimensional electron gas and graphene is investigated. On the other hand, the spin dynamics of microcavity exciton-polaritons is simulated under a magnetic field applied normally to the cavity plane and spin-orbit interaction as well. In both cases, the externally applied fields are shown to substantially change the transport properties. For the work on the two dimensional electron gas and graphene, standard approaches such as the Boltzmann transport equation and Kubo formalism were employed. The polariton spin polarization patterns were calculated using the previously developed pseudospin formalism and a coherent Schrödinger type equation accounting for pump and decay.
