Consistent perturbation expansions in screened interactions
Abdallah Arthur El Sahili, Francesco Sottile, Lucia Reining
Many-body perturbation theory is a powerful framework to calculate spectroscopic quantities, as well as the total energy. However, the field suffers from the fact that different fl…
Unbiased Diffusion Monte Carlo for non local operators
Carlos Rodriguez Perez, Valerio Olevano, Francesco Sottile +1
We propose a new mathematically exact method for computing unbiased Diffusion Monte Carlo (DMC) estimates of non-local operators. We demonstrate that the current state-of- the-art…
Trends in the electronic structure of borophene polymorphs
Alam Osorio, Lucia Reining, Francesco Sottile
Borophene is a two-dimensional material made out of boron atoms only. It exhibits polymorphism and different allotropes can be studied in terms of a rigid electronic structure, whe…
Total energy beyond GW : exact results and guidelines for approximations
Abdallah El-Sahili, Francesco Sottile, Lucia Reining
The total energy and electron addition and removal spectra can in principle be obtained exactly from the one-body Green's function. In practice, the Green's function is obtained fr…
Linear plasmon dispersion in single-wall carbon nanotubes and the collective excitation spectrum of graphene
C. Kramberger, R. Hambach, C. Giorgetti +12
We have measured a strictly linear pi-plasmon dispersion along the axis of individualized single wall carbon nanotubes, which is completely different from plasmon dispersions of gr…
