In-plane magnetization orientation driven topological phase transition in OsCl monolayer
Ritwik Das, Subhadeep Bandyopadhyay, Indra Dasgupta
The quantum anomalous Hall effect resulting from the in-plane magnetization in the OsCl monolayer is shown to exhibit different electronic topological phases determined by the…
Effect of Spin Orbit Coupling in non-centrosymmetric half-Heusler alloys
Kunal Dutta, Subhadeep Bandyopadhyay, Indra Dasgupta
Spin-orbit coupled electronic structure of two representative non-polar half-Heusler alloys, namely 18 electron compound CoZrBi and 8 electron compound SiLiIn have been studied in…
Exchange interactions and spin dynamics in the layered honeycomb ferromagnet CrI
Subhadeep Bandyopadhyay, Finn Lasse Buessen, Ritwik Das +4
We derive the microscopic spin Hamiltonian for rhombohedral CrI using extensive first-principles density functional theory (DFT) calculations which incorporate spin-orbit coupl…
Bulk Rashba spin splitting and Dirac surface state in -type (BiSbSe single crystal
P. K. Ghose, S. Bandyopadhyay, T. K. Dalui +7
We report bulk Rashba spin splitting (RSS) and associated Dirac surface state in (BiSbSe, exhibiting dominant -type conductivity. We argue from the synchr…
Superconductivity in Infinite-layer Nickelates : Role of Non-zero f-ness
Subhadeep Bandyopadhyay, Priyo Adhikary, Tanmoy Das +2
Employing first-principles density functional theory calculations and Wannierization of the low energy band structure, we analyze the electronic structure of undoped, infinite-laye…
Orbital Selective Superconductivity in a Two-band Model of Infinite-Layer Nickelates
Priyo Adhikary, Subhadeep Bandyopadhyay, Tanmoy Das +2
In the present study, we explore superconductivity in NdNiO and LaNiO employing a first-principles derived low-energy model Hamiltonian, consisting of two orbitals: Ni $x^{…
