Benjamin Hunt

Carnegie Mellon University
Ph.D., Physics, Cornell University, 2009

Benjamin “Ben” Hunt received his B.S. in Physics from McGill University in his native Canada followed by his Ph.D. in Physics from Cornell University. After a postdoc at MIT, he joined the Columbia University as a Research Associate and then Carnegie Mellon University in 2015 as an Assistant Professor of Physics. He was a key contributor in a breakthrough study that demonstrated a unique band gap in a heterostructure of graphene and hexagonal boron nitride and the emergence of a fractal phenomenon in the electronic structure called the Hofstadter butterfly. This finding could lead to the development of the material for functional transistors.


I am broadly interested in condensed-matter physics, but particularly in the way that electrons behave when they are subjected to extreme conditions such as ultra-low temperatures and high magnetic fields. Under such conditions, electrons can display striking collective quantum behavior such as superconductivity, fractionalization of charge, and crystallization. Currently, we are investigating phenomena such as these by studying:
The physics of low-dimensional structures, especially “van der Waals heterostructures” of two-dimensional crystals (the most familiar of which is graphene), which we build in the lab and then fashion into mesoscopic devices using nanofabrication techniques, and
A variety of methods for probing these mesoscopic devices, such as electronic transport, capacitance, tunneling spectroscopy, and shot noise.
