Nonrelativistic and Relativistic Contributions to Spin-Momentum Locking and Spin Photogalvanic Effect in an Altermagnetic Multiferroic
Giuseppe Cuono, Subhadeep Bandyopadhyay, Amar Fakhredine +6
Altermagnetic multiferroics provide a platform where non-relativistic spin-momentum locking (SML) coexists with relativistic spin textures, yet disentangling their different origin…
Design of altermagnetism in oxide superlattices exploiting interface effects and quantum confinement
Subhadeep Bandyopadhyay, Rossitza Pentcheva
The discovery of altermagnetism has initiated intensive research and opened new avenues for spin- tronic and transport applications. While current efforts are mostly focused on bul…
Why is the -Wave spin splitting in CuF bulk-like?
Muskan, Subhadeep Bandyopadhyay, Sayantika Bhowal
With the advent of nonrelativistic spin splitting in collinear compensated antiferromagnets, several candidate materials have also been proposed, among which the family of transiti…
A Universal Framework for Controlling Non-Relativistic Spin Splitting
Aniruddha Ray, Subhadeep Bandyopadhyay, Sayantika Bhowal
Non-relativistic spin splitting in antiferromagnets has recently attracted considerable attention. Here we present a universal framework for controlling such spin splitting by iden…
Designing Non-Relativistic Spin Splitting in Oxide Perovskites
Subhadeep Bandyopadhyay, Silvia Picozzi, Sayantika Bhowal
We investigate the role of atomic distortions in non-relativistic spin splitting in perovskite oxides with Pbnm symmetry. Using LaMnO3 as a representative material, we analyze its…
Bulk photovoltaic effect in ferroelectric and antiferroelectric phases of antimony sulphoiodide investigated by means of ab-initio simulations
Giuseppe Cuono, Subhadeep Bandyopadhyay, Andrea Droghetti +1
We employ first-principles calculations to investigate the ferroelectric properties and the bulk photovoltaic effect (BPVE) of antimony sulfur iodide (SbSI). The BPVE enables direc…
Rational Control of Magnonic and Electronic Band Splittings
Subhadeep Bandyopadhyay, Anoop Raj, Philippe Ghosez +2
We provide a theoretical demonstration of controllable non-relativistic spin splitting in both electronic and magnonic bands via targeted structural distortions tied to specific ph…
Structurally triggered orbital and charge orderings in TlMnO and related compounds
Subhadeep Bandyopadhyay, Philippe Ghosez
Rare earth perovskites (MO), with electronic occupation of the M states, display different types of metal-insulator transition. For manganites (M=Mn)…
Latent electronic (anti-)ferroelectricity in BiNiO
Subhadeep Bandyopadhyay, Philippe Ghosez
BiNiO exhibits an unusual metal-insulator transition from to that is related to charge ordering at the Bi sites, which is intriguingly distinct from the…
