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…
