Silicene on Ag(111): an honeycomb lattice without Dirac bands
Sanjoy Kr. Mahatha, Paolo Moras, Valerio Bellini +4
The discovery of (4x4) silicene formation on Ag(111) raised the question on whether silicene maintains its Dirac fermion character, similar to graphene, on a supporting substrate.…
First-principles calculation of x-ray dichroic spectra within the full-potential linearized augmented planewave method: An implementation into the Wien2k code
Lorenzo Pardini, Valerio Bellini, Franca Manghi +1
X-ray absorption and its dependence on the polarization of light is a powerful tool to investigate the orbital and spin moments of magnetic materials and their orientation relative…
Effects of electronic correlation on X-Ray absorption and dichroic spectra at L edge
L. Pardini, V. Bellini, F. Manghi
We present a new theoretical approach to describe X-Ray absorption and Magnetic Circular Dichroism spectra in the presence of e-e correlation. Our approach provides an unified pict…
Quantitative determination of spin-dependent quasiparticle lifetimes and electronic correlations in hcp cobalt
J. Sanchez-Barriga, J. Minar, J. Braun +13
We report on a quantitative investigation of the spin-dependent quasiparticle lifetimes and electron correlation effects in ferromagnetic hcp Co(0001) by means of spin and angle-re…
The coordination dependence of electric-field gradients and hyperfine fields at 5sp impurities on fcc metal surfaces
S. Cottenier, V. Bellini, M. Cakmak +2
We present a comparison between accurate \textit{ab initio} calculations and a high-quality experimental data set (1986-2002) of electric-field gradients and magnetic hyperfine fie…
Structure optimization effects on the electronic properties of BiSrCaCuO
V. Bellini, F. Manghi, T. Thonhauser +1
We present detailed first-principles calculations for the normal state electronic properties of the high T superconductor BiSrCaCuO, by means of the linearized…
