Effects of short-range interactions on transport through quantum point contacts: A numerical approach
Effects of short-range interactions on transport through quantum point contacts: A numerical approach
We study electronic transport through a quantum point contact, where the interaction between the electrons is approximated by a contact potential. Our numerical approach is based on the nonequilibrium Green-function technique which is evaluated at the Hartree-Fock level. We show that this approach allows us to reproduce relevant features of …
