Welcome to my homepage

I am a Ph.D. (Prime Minister Research Fellow) scholar at the Department of Physics of IIT Madras. Currently, I am working on theoretical condensed matter physics and quantum computation. I am studying the electronic structures, transport properties, and magnetic properties of various many-body systems (e.g., strongly correlated systems, topological insulators, skyrmions, etc.) using ab-initio calculations and model Hamiltonian approach. I also work on quantum image processing and variational quantum algorithms.

New article: Tuning the band topology and topological Hall effect in skyrmion crystals via the spin-orbit coupling

In this work, we have developed comprehensive theories for electron motion in the emergent magnetic field of skyrmions and present some striking fundamental discoveries. An optimal SOC, caused by the external fields (Rashba, Dresselhaus, etc.), replicates the quantum Hall effect with prominent plateaus in the topological Hall conductivity (THC). A varying SOC tunes the skyrmion field to (a) make a transition from ordinary to Chern insulator, (b) flip the direction of edge current in the Chern insulating state, and (c) reverse the sign of THC. Our demonstration of precise control over charge transport will lead to designing of new skyrmion-based quantum devices.

New article: Deterministic role of chemical bonding in the formation of altermagnetism: Reflection from the correlated electron system NiS

Our latest article on altermagnetism has been published in Phys. Rev. B. This paper goes beyond the symmetry based binary descriptors and examines the underlying mechanism of altermagnetism from the lens of chemical bonding. We demonstrate how chemical bonding driven by the non-magnetic atoms makes the two antiferromagnetic sublattices unidentical, leading to the breakdown of antiferromagnetic band degeneracy and the formation of momentum-dependent spin-splitting. The results are relevant to establish chemical bonding driven selection rules to design tunable altermagnetic materials. As the prototype considered is the correlated electron system NiS, the present study provides deeper insight into the relation between the altermagnetic spin splitting strength and onsite Coulomb repulsion.
