Query: Resonant laser excitation of molecular wires   We investigate the influence of external laser excitations on the average
current through bridged molecules. For the computation of the current, we use a
numerically very efficient formalism that is based on the Floquet solutions of
the time-dependent molecule Hamiltonian. It is found that the current as a
function of the laser frequency exhibits characteristic peaks originating from
resonant excitations of electrons to bridge levels which are unoccupied in the
absence of the radiation. The electrical current through the molecule can
exhibit a drastic enhancement by several orders of magnitude.
