Ab-initio analysis of plasmon dispersion in sodium under pressure
J. Ibañez-Azpiroz, B. Rousseau, A. Eiguren +1
We present an ab-initio study of the electronic response function of sodium in its 5 known metallic phases from 0 to 180 GPa at room temperature. The considered formalism is based…
Relativistic effects and fully spin-polarized Fermi surface at the Tl/Si(111) surface
Julen Ibañez-Azpiroz, Asier Eiguren, Aitor Bergara
We present a detailed analysis of the relativistic electronic structure and the momentum dependent spin-polarization of the Tl/Si(111) surface. Our first principle calculations rev…
Self-consistent tight-binding description of Dirac points moving and merging in two dimensional optical lattices
Julen Ibañez-Azpiroz, Asier Eiguren, Aitor Bergara +2
We present an accurate ab initio tight-binding model, capable of describing the dynamics of Dirac points in tunable honeycomb optical lattices following a recent experimental reali…
Spin-flip transitions and departure from the Rashba model in the Au(111) surface
Julen Ibañez-Azpiroz, Aitor Bergara, Evgeny Ya. Sherman +1
We present a detailed analysis of the spin-flip excitations induced by a periodic time-dependent electric field in the Rashba prototype Au(111) noble metal surface. Our calculation…
