We perform research in theoretical condensed matter physics, including quantum information processing, computational physics, transport phenomena, energy conversion and solar energy, as well as the dynamics of complex systems. Our research work is interdisciplinary and also explores the interface between atomic physics, quantum optics, nano-science, quantum information, and computing. We are also studying optics, nanophotonics, artificial photosynthesis, light-to-electricity conversion, nano-mechanics, hybrid quantum electro-mechanical systems, quantum nano-electronics and quantum emulators. Particular emphasis is being placed on superconducting Josephson-junction qubits, scalable quantum circuitry and improved designs for their quantum control. An underlying theme of our work is to better understand nano-scale quantum systems and devise methods to control them. We use physical models to make predictions that can be tested experimentally and that can be used to better understand the observed phenomena.
