Title: Topological quantum materials and interdisciplinary quantum materials research at UA
Abstract: In the first part of this talk, I will introduce a connection between the physical properties of certain materials and the mathematical field of topology. In these “topological quantum materials,” physical properties are extraordinarily robust again small imperfections in the materials, just as shapes with distinct topological classifications remain distinct when subjected to changes that do not tear or poke holes in the shape. My goal in the first part will be to develop a more precise statement of this analogy. In the second part of the talk, I will introduce efforts at UA to create a large, interdisciplinary team of researchers working to apply physics, mathematics, electrical engineering, and computer science to advance quantum materials science and utilize those materials for applications in quantum information science.
Bio: JHugh Churchill is an assistant professor of Physics at the University of Arkansas. He received a Ph.D. in Physics from Harvard University in 2012, and before joining UA in 2015, he held a Pappalardo Fellowship at the Massachusetts Institute of Technology. At UA, the Churchill Lab combines expertise in nanofabrication with quantum transport and optoelectronic characterization to investigate the electronic, magnetic, and optical properties of atomically thin 1D and 2D semiconductor quantum devices. Current research interests include qubits based on spin and valley degrees of freedom as well as unconventional magnetic, topological, and optoelectronic properties of layered materials. Churchill is a recipient of early career awards from NSF and AFOSR, including the PECASE in 2019.
