Research Interests:

Theoretical and Computational studies in:

• Electrons on a curved manifold: Electronic and optical properties of nanoscale toroidal quantum ring structures.
• Metamaterials, nanoplasmonics and quantum control theory: Manipulation of optical excitations and transitions in carbon nanotube rings.
• Theory of exciton generation, charge separation and charge transport in organic photovoltaic cells and related biological systems and materials.

Methodology:

• Tightbinding non-equilibrium Green’s function approach with GW approximation for calculation of exciton dynamics in carbon nanotube and graphene based nanostructures.
• Hubbard model description of exciton and bi-exciton dynamics on carbon nanostructures under optical excitation.
• Access to high-performance computing.
