We discuss an extension of our earlier work on the time-dependent Landauer--B\"uttiker formalism for noninteracting electronic transport. The formalism can without complication be extended to superconducting central regions since the Green's functions in the Nambu representation satisfy the same equations of motion which, in turn, leads to the same closed expression for the equal-time lesser Green's function, i.e., for the time-dependent reduced one-particle density matrix. We further write the… Expand

Partition-free theory of time-dependent current correlations in nanojunctions in response to an arbitrary time-dependent bias

Dynamical Coulomb blockade and the derivative discontinuity of time-dependent density functional theory.
This work follows the time evolution of an interacting nanojunction attached to biased leads and finds that, instead of evolving to a steady state, the system reaches a dynamical state characterized by correlation-induced current oscillations. Expand

Coulomb blockade of two-electron tunneling.
The Coulomb blockade in a superconducting grain connected to two normal electrodes by tunnel junctions is studied, where the current first grows linearly with the applied bias and then drops as the quasiparticle transport channel opens up. Expand
