Biography

Professor Fahad Mahmood is an experimentalist in condensed matter physics. He will be starting his research lab on the femtosecond manipulation of quantum materials at the University of Illinois in August 2019. He received his B.S. from Stanford University in 2010, majoring in Physics and Aero/Astro Engineering. He went on to receive his PhD in Physics from the Massachusetts Institute of Technology in 2016, working in the group of Nuh Gedik. There, he developed ultrafast optical and photoemission techniques to study and control emergent phenomena in a variety of quantum materials. From 2016 to 2019, Professor Mahmood was a postdoctoral research fellow in the group of Peter Armitage at Johns Hopkins University. His research utilized THz range spectroscopies to probe complex interactions in high-temperature and unconventional superconductors, and frustrated quantum magnets at their natural energy scales.

Research Statement

Professor Fahad Mahmood's research lab at the University of Illinois will develop and apply non-linear optical and time-resolved photoemission spectroscopies to solve problems at the intersection of strongly correlated quantum materials and non-equilibrium phenomena. One of the principal goals is to use laser light to engineer electronic interactions in materials, probe their spatial and temporal correlations, and realize model Hamiltonians and novel phases of matter.

Typical experiments will utilize a laser pulse to perturb a particular material in different ways, e.g., by coupling to charge or spin degrees of freedom, exciting specific collective modes or modifying the local energy landscape over short (femtosecond) timescales. Custom-built spectroscopic tools such as time-resolved ARPES and time-domain THz spectroscopy will then be used to examine the resulting evolution of electronic states, measure changes in low-energy electrodynamics and disentangle coupled excitations. Projects and materials will be varied but will likely include unconventional superconductors, topological systems and frustrated magnets.
