I am a scientist studying the physics of materials, as a postdoctoral scholar at Harvard University. My research is focused on materials that exhibit quantum mechanical phenomena over a wide range of energy and length scales. I use light as a means of unraveling their complex phenomenology and manipulating their behavior.

Research highlights

Magnetism when combined with topological materials can give rise to new electronic phases – if they interact with each other. Here, we study a material where magnetism coexists with topological bands, and quantify the exchange coupling between the two.

Magnetism in topological materials creates a platform to realize spin-based phenomena with applications in spintronics, memory, and quantum information. Here, we discover a new knob to control interlayer magnetic bonding in an antiferromagnetic topological insulator – phonons.

Polar metals are materials that simultaneously demonstrate polar order and metallicity, two seemingly incompatible properties. In this work, we outline the mechanism that may stabilize such a state, and observe experimental signatures of this using optical spectroscopy.

Multiferroic materials with simultaneous ferroelectric and magnetic order offer the prospect of electric-field control of magnetism. Our new symmetry-based approach helps us identify hidden magnetoelectric switching pathways in BiFeO3, clarifying its deterministic nature.

Graphene with a vacancy defect is a unique system that is magnetic even in the absence of magnetic ions. Here, we use first-principles calculations to show that this magnetism is intertwined with local structural deformations, with non-planarity quenching the magnetic moment.
