Excitonic instability and unconventional pairing in the nodal-line materials ZrSiS and ZrSiSe

We use a functional renormalization group (fRG) approach to investigate potential interaction-induced instabilities in a two-dimensional model for the Dirac nodal-line materials ZrSiS and ZrSiSe employing model parameters derived from ab initio calculations. Our results characterize the excitonic in...
