Research activities
I am a condensed-matter physicist using theoretical and
computational tools to study the properties of materials from
first-principles ("ab initio"). My work often involves
the development of novel theoretical formulations and
algorithms, and their application to interesting materials. I
have introduced methods to study insulators in finite electric
fields, and to construct localized Wannier orbitals for metals.
Currently I am studying the ground-state and transport
phenomena that arise from broken symmetries such as time
reversal (magnetic order) and spatial inversion. Examples
include the anomalous
Hall effect and orbital magnetization in ferromagnetic metals,
the valley Hall effect in transition-metal dichalcogenides, and
magnetoelectric effects in topological insulators, magnetic
oxides, and gyrotropic metals. A recurring theme in my research
is the use of quantum-geometric concepts (Berry phase and
curvature, Chern number, intrinsic orbital moment, quantum
metric) to describe the electronic properties of solids.
