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…
