Ab initio formulation of the four-point conductance of interacting electronic systems

Article English OPEN
Bokes, P.; Jung, J.; Godby, R. W.;

We derive an expression for the four-point conductance of a general quantum junction in terms of the density response function. Our formulation allows us to show that the four-point conductance of an interacting electronic system possessing either a geometrical constric... View more
