Nonrelativistic spin splittings and altermagnetism in twisted bilayers of centrosymmetric antiferromagnets
Sajjan Sheoran, Saswata Bhattacharya
Magnetism-driven nonrelativistic spin splittings (NRSS) are promising for highly efficient spintronics applications. Although 2D centrosymmetric (in four-dimensional spacetime) ant…
Accelerated Neural Network Training through Dimensionality Reduction for High-Throughput Screening of Topological Materials
Ruman Moulik, Ankita Phutela, Sajjan Sheoran +1
Machine Learning facilitates building a large variety of models, starting from elementary linear regression models to very complex neural networks. Neural networks are currently li…
Multiple Zeeman-type Hidden Spin Splitting in -Symmetric Layered Antiferromagnets
Sajjan Sheoran, Saswata Bhattacharya
Centrosymmetric antiferromagnetic semiconductors, although abundant in nature, appear less favorable in spintronics owing to the lack of inherent spin polarization and magnetizatio…
Strain-driven topological quantum phase transition in the family of halide perovskites
Ankita Phutela, Sajjan Shoeran, Saswata Bhattacharya
The centrosymmetric halide perovskites undergo a continuous phase transition from a normal insulator to a topological insulator at the critical value of strain. Contrarily, in nonc…
Probing the uniaxial strain-dependent valley drift and Berry curvature in monolayer MoSiN
Sajjan Sheoran, Saswata Bhattacharya
We use ab initio calculations and theoretical analysis to investigate the influence of in-plane strain field on valley drifts and Berry curvatures in the monolayer MoSiN, a…
Manipulation of valley and spin properties in two-dimensional Janus WSiGeZ (Z=N,P, As) through symmetry control
Sajjan Sheoran, Ankita Phutela, Ruman Moullik +1
A class of septuple-atomic-layer two-dimensional (2D) materials, MAZ, is sought as an alternative to 2D hexagonal transition metal dichalcogenides in the field of valleytro…
