Accurate self-energy algorithm for quasi-1D systems
Ivan Rungger, Stefano Sanvito
We present a complete prescription for the numerical calculation of surface Green's functions and self-energies of semi-infinite quasi-onedimensional systems. Our work extends the…
Electrically-driven phase transition in magnetite nanostructures
Sungbae Lee, Alexandra Fursina, John T. Mayo +5
Magnetite (FeO), an archetypal transition metal oxide, has been used for thousands of years, from lodestones in primitive compasses[1] to a candidate material for magne…
On the Newtonian origin of the spin motive force in ferromagnetic atomic wires
Maria Stamenova, Tchavdar N. Todorov, Stefano Sanvito
We demonstrate numerically the existence of a spin-motive force acting on spin-carriers when moving in a time and space dependent internal field. This is the case of electrons in a…
Exchange parameters from approximate self-interaction correction scheme
A. Akande, S. Sanvito
The approximate atomic self-interaction corrections (ASIC) method to density functional theory is put to the test by calculating the exchange interaction for a number of prototypic…
