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