Advanced Quantum Transport, Interactions, and
Control
The goal of my group’s research is to engineer semiconductor nanosystems where quantum transport of
charge leads to new electronic properties and devices, and where quantum interactions can be controlled
and studied. Systems of interest are quantum wires, quantum wells, the quantum Hall effect, and
thermoelectric phemonema in nanoengineered systems. The quantum numbers to be manipulated are the
spin index, valley index, and layer index in multilayer systems, measured at low temperatures and high
magnetic fields where Luttinger liquids, quantum Hall ferromagnets, and multi-valley systems can be
probed. This research will have applications in quantum information processing and cryogenic
thermoelectrics.
