Modeling excitons in bulk and single-layer hBN

New paper on excitations in hexagonal Boron-Nitride. Core and low energy electronic excitations have been studied in hexagonal boron nitride by means of angular resolved electron energy loss spectroscopy and theoretical calculations.

RPA calculations with Yambo for large systems

Performing RPA calculations with yambo in large systems can be a problem due to the memory requirement. In fact the code does not distribute the dielectric constant at the different frequencies among the processors. The solution is to run different calculations for each frequency of the dielectric constant and then joind the outputs. Here my… Read More
