Exploring approximations to the GW selfenergy ionic gradients
A new paper is out on the different approximation in GW for the electronphonon couping matrix elements. In particular we tested two approximation the static screening (COHSEX) and the constant screening respect to the phonon displacement. We found that the first approximation miserably fails to reproduce the G0W0 results while the second introduce a negligible […]

Graphene research is slowly fading away
After the discover of graphene in 2014 by Geim and Novoselov that got the Nobel price in 2010, scientists have worked hard to investigate all possible properties and possible uses of this material. At the beginning graphene was proposed as possible candidate to substitute silicon in electronics, due its extreme high conductivity. However differently from […]

Computer Simulations for condensed phase systems: from correlated electrons to novel materials
Dear Friends and Colleagues, in the occasion of Giovanni Bachelet’s 60th birthday, you are warmly invited to the workshop “Computer Simulations for condensed phase systems: from correlated electrons to novel materials” to be held at the CNR Headquarters in Rome, on May 46, 2015. The talks, on invitation only, will be given by […]
