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…
Inter-chain Interactions, Multi-magnon condensation and Strain effect in chain compound NaVOPO
Manoj Gupta, Manodip Routh, Manoranjan Kumar +1
Employing first-principles modelling and many-body methods, the magnetic properties of spin-1/2 chain compound NaVOPO are explored. The extensive first-principles calculations…
Ab-initio Insights on the Fermiology of Transition metals in Honeycomb lattice : Hierarchy of hopping pathways and spin-orbit coupling
Manoj Gupta, Basudeb Mondal, Subhro Bhattacharjee +1
Motivated by the intriguing suggestion of realizing SU(8) Dirac semi-metal with electrons on a honeycomb lattice, we provide a systematic study of the interplay of various…
