'''EXC'''<ref>[http://www.bethe-salpeter.org http://www.bethe-salpeter.org]</ref> is a [[condensed matter physics]] [[many-body theory]] [[Software package (installation)|software package]] implementing the [[Bethe–Salpeter equation]] in frequency-reciprocal space and on a [[plane wave]] basis set. Its purpose is to calculate, [[ab initio]], dielectric and optical properties, like [[optical absorption|absorption]], [[reflectivity]], [[refraction index]], electron and X-ray [[Electron energy loss spectroscopy|energy loss]], for a large variety of systems, ranging from bulk systems, surfaces, to clusters or atoms.
