Antiferromagnetically ordered Dirac semimetal in Hubbard model with spin-orbit coupling
Garima Goyal, Dheeraj Kumar Singh
We examine the possible existence of Dirac semimetal with magnetic order in a two-dimensional system with a nonsymmorphic symmetry by using the Hartree-Fock mean-field theory withi…

Semimetallic spin-density wave state in iron pnictides
Garima Goyal, Dheeraj Kumar Singh
We examine the existence of semimetallic spin-density wave states in iron pnictides. In the experimentally observed metallic spin-density wave state, the symmetry-protected Dirac c…

Hund's coupling and electronic anisotropy in the spin-density wave state of iron pnictides
Garima Goyal, Dheeraj Kumar Singh
In the multiband systems, Hund's coupling () plays a significant role in the spin and charge excitations. We study the dependence of electronic anisotropy on in terms of Dru…
