Ab initio GW many-body effects in graphene
P. E. Trevisanutto, C. Giorgetti, L. Reining +2
We present an {\it ab initio} many-body GW calculation of the self-energy, the quasiparticle band plot and the spectral functions in free-standing undoped graphene. With respect to…
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…
Ab-initio calculations of Many-Body effects in liquids: the electronic excitations of water
V. Garbuio, M. Cascella, L. Reining +2
We present ab-initio calculations of the excited state properties of liquid water in the framework of Many-Body Green's function formalism. Snapshots taken from molecular dynamics…
Beyond time-dependent exact-exchange: the need for long-range correlation
Fabien Bruneval, Francesco Sottile, Valerio Olevano +1
In the description of the interaction between electrons beyond the classical Hartree picture, bare exchange often yields a leading contribution. Here we discuss its effect on optic…
Optical absorption in small BN and C nanotubes
L. Wirtz, V. Olevano, A. G. Marinopoulos +2
We present a theoretical study of the optical absorption spectrum of small boron-nitride and carbon nanotubes using time-dependent density-functional theory and the random phase ap…
