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

M. M. Scherer, C. Honerkamp, A. N. Rudenko +3

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 Zr…
