Questaal: a package of electronic structure methods based on the linear muffin-tin orbital technique
Dimitar Pashov, Swagata Acharya, Walter R. L. Lambrecht +5
This paper summarises the theory and functionality behind Questaal, an open-source suite of codes for calculating the electronic structure and related properties of materials from…
GW correlation effects on plutonium quasiparticle energies: changes in crystal-field splitting
A. N. Chantis, R. C. Albers, A. Svane +1
We present results for the electronic structure of plutonium by using a recently developed quasiparticle self-consistent method (\qsgw). We consider a paramagnetic solution wi…
Ab-initio calculations of spin tunneling through an indirect barrier
Athanasios N Chantis, Titus Sandu, Jialei L Xu
We use a fully relativistic layer Green's functions approach to investigate spin-dependent tunneling through a symmetric indirect band gap barrier like GaAs/AlAs/GaAs heterostructu…
Prediction of large linear-in-k spin splitting for holes in the 2D GaAs/AlAs system
Jun-Wei Luo, Athanasios N. Chantis, Mark van Schilfgaarde +2
The spin-orbit interaction generally leads to spin splitting (SS) of electron and hole energy states in solids, a splitting that is characterized by a scaling with the wavevector $…
Detection of the spin character of Fe(001) surface states by scanning tunneling microscopy: A theoretical proposal
Athanasios N. Chantis, Darryl L. Smith, J. Fransson +1
We consider the magnetic structure on the Fe(001) surface and theoretically study the scanning tunneling spectroscopy using a spin-polarized tip (SP-STM). We show that minority-spi…
Theory of electrical spin-detection at a ferromagnet/semiconductor interface
Athanasios N. Chantis, Darryl L. Smith
We present a theoretical model that describes electrical spin-detection at a ferromagnet/semiconductor interface. We show that the sensitivity of the spin detector has strong bias…
