Abstract:
Semiconductors have been the “go-to” material over the past five decades for classical information science and microelectronics technology. They may very well continue their primacy in the quantum era. Indeed, by making compound semiconductor heterostructures a new quantum materials platform, future quantum information science (QIS) and quantum microelectronics applications can build on, and be compatible with, the sophistication and maturity of state-of-the-art semiconductor synthesis and processing. In this talk, I will present our recent work aiming to advance the field of artificial quantum materials for QIS and quantum microelectronics by exploring electron correlation physics and topological phenomena in artificial quantum materials composed entirely of conventional compound semiconductor InAs/GaSb heterostructures. We will show that these artificial quantum materials can enable discoveries of new quantum phenomena.

Bio:
Dr. Wei Pan is a Distinguished Member of the Technical Staff at Sandia National Laboratories. He obtained his Ph.D. degree in physics from Princeton University. He has made numerous seminal contributions to the field of many-particle physics in low dimensional electron systems (in particular novel fractional quantum Hall effect), and in topological superconductivity and Josephson effects in Dirac semimetals. He is the author of more than 100 papers in technical journals. He was a member of the Organizing and Program committees of the 16th International Conference on Electronic Properties of Two-Dimensional System (EP2DS-16), a member of the Program Committee of the 21st International Conference on High Magnetic Fields in Semiconductor Physics (HMF21) and the 8th Physical Phenomena in High Magnetic Fields Conference (PPHMF-8). He was awarded the 2007 Presidential Early Career Award for Scientists and Engineers (PECASE).
