## Photon-assisted transmission through an oscillating quantum well: A transfer-matrix approach to coherent destruction of tunneling

Based on a trasfer-matrix formalism, photon-assisted tunneling is studied in a strongly driven double-barrier tunneling diode. Two scenarios are considered: A driving potential [ital V][sub 1]cos([omega][ital t]) acting on the central quantum well, which may be realized with electrostatic gates close to the quantum well, and a driving electric field across the diode generated by a laser field. Strong quenching of the transmission probability is found for certain parameters [l brace][ital V][sub 1],[omega][r brace] of the driving field, which can be explained in terms of zeros of fractional Bessel functions, [ital J][sub [plus minus][nu]]([gamma][ital V][sub 1]/[h bar][omega]), where [gamma] ismore »
