Photon assisted longrange tunneling
Abstract
We analyze longrange transport through an ac driven triple quantum dot with a single electron. Resonant transitions between separated and detuned dots are mediated by the exchange of n photons with the timedependent field. An effective model is proposed in terms of second order (cotunneling) processes which dominate the longrange transport between the edge quantum dots. The ac field renormalizes the inter dot hopping, modifying the level hybridization. It results in a nontrivial behavior of the current with the frequency and amplitude of the external ac field.

Observation of photonassisted tunneling through a quantum dot
We have measured dc transport through a GaAs/AlGaAs quantum dot in the presence of a microwave signal of frequency [ital f]. We find features related to the photon energy [ital hf] whose positions in gate voltage are independent of the microwave power buy vary linearly with frequency. The measurements demonstrate photonassisted tunneling in the mesoscopic regime. A comparison is made with a model that extends Coulomb blockade theory to include photonassisted tunneling. 
Photonassisted resonant tunneling through a doublebarrier structure for infrared radiation detection
A Green'sfunction approach is employed to calculate the electron tunneling through a doublebarrier device for infraredradiation detection. Electrons photoexcited by an ir beam undergo transitions to a resonant channel, so that the transmission coefficient for tunneling substantially increases by several orders of magnitude compared with the dark state. This photoninduced resonant tunneling can be switched and controlled by a change of the applied static voltage. Such a system is ideal for ir photodetectors. 
Photonassisted transmission through an oscillating quantum well: A transfermatrix approach to coherent destruction of tunneling
Based on a trasfermatrix formalism, photonassisted tunneling is studied in a strongly driven doublebarrier 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 » 
Negative dynamic conductance from photonassisted tunneling in superconducting junctions
We show that a superconductorinsulatorsuperconductor (SIS) junction may exhibit regions of negative dynamic conductance if it is irradiated by a timevarying signal source which deviates from the conventionally treated constant ac voltage limit. This phenomenon reflects the strong dependence of the junction absorption cross section upon dc bias voltage. Analytic estimates for the magnitude of the negative conductance and its impact upon the frequency down conversion process are obtained in the constant ac current limit.
