Quantum Materials and Devices

Main Content

Summary

Our research spans from exploring basic Physics in reduced dimensionality systems to building novel devices for applications. From a fundamental Physics standpoint, small is often different. A prime example of this is the difference between the quantum and the classical worlds. We seek to gain fundamental understanding of quantum effects and other novel Physics at nanoscales. Charge, spin and thermal transport measurements performed at low-temperatures in our lab offer a versatile probe into these properties. The unique insights uncovered by these studies are used to guide material and device design for different applications.

Ongoing projects include measuring speed limits of quantum entanglement, thermoelectric effects at cryogenic temperatures, and the impact of phonon engineering on spin relaxation and decoherence.

We are always looking for motivated undergraduate and graduate students to join our group. The best time to contact me if you are intersted in working in the group is February for undergrads and September through November for graduate students.
