Polarization-dependent excitons and plasmon activity in nodal-line semimetal ZrSiS
Polarization-dependent excitons and plasmon activity in nodal-line semimetal ZrSiS
The optical properties of the bulk ZrSiS nodal-line semimetal are theoretically studied within a many-body formalism. The G0W0 bands are similar to those calculated within the density functional theory, except near the Γ-point; in particular, no significant differences are found around the Fermi energy. On the other hand, the solution …
