Anomalous Tien-Gordon scaling in a 1d tunnel junction
Gianaurelio Cuniberti, Andrea Fechner, Maura Sassetti +1
We investigate the nonlinear ac transport through a quantum wire with an impurity in the presence of finite range electron-electron interactions. We discuss the influence of the sp…

Local fields in nonlinear quantum transport
Andrea Fechner, Gianaurelio Cuniberti, Maura Sassetti +1
We investigate the dynamical interplay between currents and electromagnetic fields in frequency-dependent transport through a single-channel quantum wire with an impurity potential…

Frequency scaling of photo-induced tunneling
Gianaurelio Cuniberti, Andrea Fechner, Maura Sassetti +1
The DC current-voltage characteristics, induced by a driving electric field with frequency Omega, of a one dimensional electron channel with a tunnel barrier is calculated. Electro…
