Efficient ab initio calculations of bound and continuum excitons
Francesco Sottile, Marherita Marsili, Valerio Olevano +1
We present calculations of the absorption spectrum of semiconductors and insulators comparing various approaches: (i) the two-particle Bethe-Salpeter equation of Many-Body Perturba…

Transforming nonlocality into frequency dependence: a shortcut to spectroscopy
Matteo Gatti, Valerio Olevano, Lucia Reining +1
Measurable spectra are theoretically very often derived from complicated many-body Green's functions. In this way, one calculates much more information than actually needed. Here w…
