We discuss an extension of our earlier work on the time-dependent Landauer–
Büttiker 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 finite-temperature frequency integrals in terms
of known special functions thereby considerably speeding up the computation. Simulations in
simple normal metal – superconductor – normal metal junctions are also presented.

Time-dependent density-functional theory for strongly interacting electrons
Cort Barrada, Luis; Karlsson, Daniel; Lani, Giovanna; van Leeuwen, Robert (American Physical Society, 2017)We consider an analytically solvable model of two interacting electrons that allows for the calculation of the exact exchange-correlation kernel of time-dependent density functional theory. This kernel, as well as ... -
