On Transmission Node Structure in Interacting Systems
Joshua D. Barr, Charles A. Stafford
We provide a series of generic results regarding the structure of nodes in the retarded Green's function G of an interacting system, as exemplified by the extended Hubbard model. I…
Effective Field Theory of Interacting π-Electrons
Joshua D. Barr, Justin P. Bergfield, Charles A. Stafford
We develop a π-electron effective field theory (π-EFT) wherein the two-body Hamiltonian for a π-electron system is expressed in terms of three effective parameters: the π-orbital q…
Transmission eigenvalue distributions in highly-conductive molecular junctions
Justin P. Bergfield, Joshua D. Barr, Charles A. Stafford
The transport through a quantum-scale device may be characterized by the transmission eigenvalues. These values constitute a junction PIN code where, for example, in single-atom me…
The number of transmission channels through a single-molecule junction
J. P Bergfield, J. D. Barr, C. A. Stafford
We calculate transmission eigenvalue distributions for Pt-benzene-Pt and Pt-butadiene-Pt junctions using realistic state-of-the-art many-body techniques. An effective field theory…
