Research Areas
We perform theoretical studies of complex dynamics in materials. We use physically-motivated models to make predictions which can be tested experimentally and are useful to better understand the observed phenomena. We are currently working on several projects, including: quantum computing (superconducting Josephson-junction qubits, scalable quantum circuitry, improved designs for their quantum control), vortex dynamics in superconductors, new fluxtronics devices, complex collective phenomena, and nano-magnatism. We are also working on biologically-inspired solid-state devices that can control the motion of quanta
