Description
We calculate the axion flux from the Sun due to axion-electron interactions by fully accounting for electron transitions between different bound states. For multiple elements, we consider a wide range of ionization and excitation states and compute the axion-induced transitions between them.\
The axion flux from axion-electron interactions is usually estimated via an approximate relation to the photon flux. However, this approach neglects magnetic-like transitions ($\Delta L=0$), which are of the same order as electric-like transitions ($\Delta L=\pm1$) for axion-induced processes.\
In this work, we instead apply tools from condensed matter physics, treating the problem as a generalized Anderson impurity model, in which the interactions are described through the self-energy or hybridization function. For photon-electron transitions, this method allows us to calculate energy shifts in atomic multiplets, such as the Lamb shift, as well as transition spectra for fluorescence or Auger-Meitner decays. A similar approach can then be applied to axion-electron interactions.
