Theoretical studies of the unique electronic and optical properties of nanostructures are being done, often in conjunction with experiment in the Branch. A range of techniques are used including many-body approaches for optical properties, ab initio electronic calculations for electronic properties and geometries, finite element techniques for complex geometries, and dynamical matrices for vibrational properties. Recent work has addressed the optical properties of single and coupled quantum dots for implementations for quantum information, quantum gates for quantum information, quantum dots in semiconductor microcavities for advanced quantum electronics, adsorption of a range of adsorbates on carbon nanotubes and it effects on conductance and capacitance for sensors.
