Review on GW and Bethe-Salpeter for molecular systems

We just published a new review on GW and Bethe-Salpeter (BSE) for molecules. In the review we discuss electronic excitations both in TDDFT and  in the Green’s function approach.  The successes and failures of the different methods are presented. In particular we focused on charge-transfer excitations for which the photoexcited electron and the hole left… Read More

Efficient Gate-tunable light-emitting device made of defective boron nitride nanotubes

I published my first “Nature”, even if the lower level one, a Nature Scientific Reports: Efficient Gate-tunable light-emitting device made of defective boron nitride nanotubes: from ultraviolet to the visible Claudio Attaccalite, Ludger Wirtz, Andrea Marini & Angel Rubio Scientific Reports 3, Article number:2698 Boron nitride is a promising material for nanotechnology applications due to… Read More

Optical excitations in a paradigmatic model dipeptide

We just post on arxiv a new paper on the optical excitations in a paradigmatic model dipeptide, here in the figure. We studied local and charge transfer excitations by means of state of the art GW and Bethe-Salpeter equations as implemented in the FIESTA code. In particular we focused on the effect of self-consistency in… Read More
