Correlated Electron Transport in Molecular Electronics [PDF]

open access: yesPhysical Review Letters, 2004
Theoretical and experimental values to date for the resistances of single molecules commonly disagree by orders of magnitude. By reformulating the transport problem using boundary conditions suitable for correlated many-electron systems, we approach electron transport across molecules from a new standpoint.
