Two-orbital model with bond-dependent spin-orbit coupling: A playground for emergent band topology, Kitaev magnetism, and magnetoelectricity
YuZheng Xie, Manoj Gupta, Arun Paramekanti +1
Inspired by the electronic structure of compounds like nickel dihalides Ni (=Cl, Br, I), we propose a low-energy two-orbital model featuring bond-dependent spin-orbit…

Multiple Dirac Spin-Orbital Liquids in SU(4) Heisenberg Antiferromagnets on the Honeycomb Lattice
Manoj Gupta, Arijit Haldar, Subhro Bhattacharjee +1
We study the strong coupling model of transition metal tri-halides in the large spin-orbit coupled limit. By considering ab-initio-calculation-inspired hierarchy of hopping p…

Role of topotactic hydrogen in Superconductivity of Infinite-layer Nickelate NdNiO: A first-principles and variational Monte Carlo study
Manoj Gupta, Arun Kumar Maurya, Amal Medhi +1
Employing combination of first-principles calculations, low-energy model construction, and variational Monte Carlo solution of the ab-initio derived Hubbard model, we study the eff…
