Weyl semimetallic state with antiferromagnetic order in Rashba-Hubbard model
Aastha Jain, Garima Goyal, Dheeraj Kumar Singh
We study the phase diagram of Rashba-Hubbard model by employing the Hartree-Fock meanfield theory, and thereby establish the existence of an antiferromagnetically ordered Weyl semi…
Non-reciprocal spin-wave excitations in Rashba-Hubbard ferromagnets
Aastha Jain, Dheeraj Kumar Singh
We explore the nonreciprocity of spin-wave excitations in the Rashba-Hubbard ferromagnet on a square lattice. Our study reveals that the propagation of spin-wave excitations exhibi…
Orbital correlations in bilayer nickelates: roles of doping and interlayer coupling
Garima Goyal, Aastha Jain, Dheeraj Kumar Singh
We study the nature of orbital correlations present in the bilayer nickelate within a minimal two-orbital tight-binding model to gain insights into their possible role in stabilizi…
Insight into interplay between bandstructure and Coulomb interaction via quasiparticle interference
Garima Goyal, Dheeraj Kumar Singh
Quasiparticle interference has been used frequently for the purpose of unraveling the electronic states in the vicinity of the Fermi level as well as the nature of superconducting…
Role of Dirac cones in the anisotropic properties associated with the spin-density wave state of iron pnictides
Garima Goyal, Dheeraj Kumar Singh
The origin of unusual anisotropic electronic properties in the spin-density wave state of iron pnictides has conventionally been attributed to the breaking of four-fold rotational…
