Hidden Order and "Altermagnetism"
In condensed matter systems, often the electronic degrees of freedom are coupled to form complex composites that give rise to unusual properties of matter while escaping detection in the conventional experiments. Such complex orders are known as "hidden" orders. Our research is dedicated to uncovering these hidden orders, exposing unconventional properties within diverse material systems, including ferroelectrics, magnetoelectrics, magnetic skyrmions, non-relativistic spin split antiferromagnets (also known as "altermagnets"), and polar metals.

Topology and Orbital Hall Transport
Recognizing the essential role of the Berry phase in describing various phenomena in solid-state physics, the focus extends to diverse Hall effects linked to the material's band structure topology. The intrigue in these Hall effects stems from both the underlying fundamental physics and their potential applications in spintronics and orbitronics. A part of our research concentrates on comprehending distinct Hall effects—viz., anomalous, spin, and orbital Hall effects—within real materials. The aim is to propose mechanisms for their control or offer guidance to explore new materials that exhibit enhanced effects, with an outlook toward potential applications.

Spin-orbit coupled magnetism
Spin-orbit effects in heavy transition metal oxides, in particular, iridates, have received enormous current interest due to the prediction as well as the realization of a plethora of exotic and unconventional magnetic properties. Our research contributes to the understanding of different unconventional magnetic properties in iridates driven by the interplay among strong spin-orbit interaction, Hund’s coupling, strong correlation, crystal field splitting, etc.
