A large part of the research activity carried out in this research focus concerns the physical mechanisms responsible for the generation and transfer of polarized radiation in the solar atmosphere, as well as the mechanisms through which the magnetic field leaves its imprints in the polarization of the electromagnetic radiation. By taking these mechanisms into account, we model the intensity and polarization profiles of given spectral lines, by solving the radiative transfer problem for polarized radiation in conditions of non-local thermodynamic equilibrium (non-LTE), in realistic models of the solar atmosphere. One of the main goals of this activity is the development of novel diagnostic methods for the investigation of the magnetic fields present in the solar atmosphere, in domains that are not accessible through the conventional techniques (generally based on the Zeeman effect) that are currently applied.
