Designing the Nanoworld: Nanostructure, Nanodevices, and Nano-optics

Ongoing
Developing and exploiting nanodevices for quantum and nanotechnologies requires nanoscale and atomic scale modeling of ultrasmall structures, devices, their operation, and their response to probes. Key challenges of understanding physics at the quantum/classical interface and measurement at the

Nanoplasmonics and Three-Dimensional Plasmonic Metamaterials

Ongoing
Plasmonic materials are composed of metals and insulators that are ordered in geometric arrangements with dimensions that are fractions of the wavelength of light. Research groups are experimenting with a variety of geometric approaches, but all aim to exploit surface plasmons, which are light

Light-matter interactions in Semiconductor Nanostructures

Ongoing
We investigate the interaction of light with semiconductor-based nanostructures. We extend concepts of entanglement and coherence in atomic physics to our solid-state systems. Our devices are based on semiconductors, like GaAs. We use InAs quantum dots (QDs) in GaAs as artificial atoms; they have
