  In this study, we show how a static magnetic field can control photon-induced
electron transport through a quantum dot system coupled to a photon cavity. The
quantum dot system is connected to two electron reservoirs and exposed to an
external perpendicular static magnetic field. The propagation of electrons
through the system is thus influenced by the static magnetic and the dynamic
photon fields. It is observed that the photon cavity forms photon replica
states controlling electron transport in the system. IF the photon field has
more energy than the cyclotron energy, then the photon field is dominant in the
electron transport. Consequently, the electron transport is enhanced due to
activation of photon replica states. By contrast, the electron transport is
suppressed in the system when the photon energy is smaller than the cyclotron
energy.
