Nonlinear optical conductance from photon-assisted tunneling in a nanoantenna-coupled tunnel diode
Paul S Davids, Erik Anderson, Jared Kirsch +1
Ultrafast photon-assisted tunneling is shown to lead to large nonlinear dynamic currents that can be used to generate dc rectified current as well as higher order harmonic response…

Density matrix approach to photon-assisted tunneling in the transfer Hamiltonian formalism
Paul S. Davids, Joshua Shank
The transfer Hamiltonian tunneling current is derived in a time-dependent density matrix formulation and is used to examine photon-assisted tunneling. Bardeen's tunneling expressio…
