Code

The Lumen code is derived from Yambo 4.1.3. Lumen implements a new approach to study non-linear response in solids and nanostructures. 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.


Differences from Yambo

  1. Since non-linear response requires double-precision to work, by default Lumen is compiled in double precision. In order to compile Lumen in single-precision use the flags --enable-sp.
  2. Old Yambo databases are not compatible with Lumen. In general please do not mix databases of Yambo and Lumen.
  3. Libxc and IotK and NetCdf libraries are already included in Lumen package.
