+Here {math}`\epsilon_{nk}` and {math}`\psi_{nk}` are the Kohn-Sham energies and wavefunctions, respectively, while $V_{xc}$ is the DFT exchange-correlation potential.
 
 For each electronic state $nk$, the self-energy can be separated into two components: a static, gap-opening term called the exchange self-energy ($\Sigma^x$), and an energy-dependent, usually gap-closing term called the correlation self-energy ($\Sigma^c$). These contributions are tackled separately by the code:
