Lumen

Lumen is a code derived from Yambo 4.1.3 that implements a new approach to study non-linear response in solids and nanostructures based on a real-time evolution of an effective Schödinger equation.



Notice that all the non-linear implementation of Lumen will be soon included in the official Yambo distribution, so if you are not in hurry to use it, just wait for the new version of Yambo.

    We have released the real-time Bethe-Sapeter code with a tutorial. Notice that RT-BSE can be used only with a local exchange (NGOscll=1) or including few g-vectors due to its high computational cost, an improved version will be released soon.
