Exciton band structure of VO
Vitaly Gorelov, Lucia Reining, Matteo Gatti
Excitonic effects due to the correlation of electrons and holes in excited states of matter dominate the optical spectra of many interesting materials. They are usually studied in…
Pseudopotential Bethe-Salpeter calculations for shallow-core x-ray absorption near-edge structures: excitonic effects in Al2O3
M. Laura Urquiza, Matteo Gatti, Francesco Sottile
We present an ab initio description of optical and shallow-core x-ray absorption spectroscopies in a unified formalism based on the pseudopotential plane-wave method at the level o…
Short-range excitonic phenomena in low-density metals
Jaakko Koskelo, Lucia Reining, Matteo Gatti
Excitonic effects in metals are commonly supposed to be weak, because the Coulomb interaction is strongly screened. We investigate the low-density regime of the homogeneous electro…
