Six from MIT named American Physical Society Fellows for 2022

Six members of the MIT community have been elected fellows of the American Physical Society for 2021. The APS Fellowship Program was created in 1921 for those in the physics community to recognize peers who have contributed to advances in physics through original research, innovative applications, teaching, and leadership. According to the APS, each year no more than one-half of 1 percent of the APS membership, excluding student members, are recognized by their peers for election to the status of fellow.

Professor Anna Frebel studies the chemical and physical conditions of the early universe, and how the oldest, still-surviving stars can be used to obtain constraints on the nature of the very first stars and early supernova explosions, and associated stellar element nucleosynthesis. She is best known for her discoveries and subsequent spectroscopic analyses of 13 billion-year-old stars in the Milky Way and ancient, faint stars in the least-luminous dwarf galaxies, to uncover unique information about the physical and chemical conditions of the early universe. The APS Division of Astrophysics elected Frebel “for pioneering contributions to the study of low-metallicity stars, near-field cosmology, and the r-process in astrophysics.”

Professor Liang Fu is interested in novel topological phases of matter and their experimental realizations. He works on the theory of topological insulators and topological superconductors, with a focus on predicting and proposing their material realizations and experimental signatures. He is also interested in potential applications of topological materials, ranging from tunable electronics and spintronics, to quantum computation. The APS Division of Condensed Matter Physics elected Fu “for pioneering contributions to the theory of topological quantum materials.”

Professor Nuh Gedik’s research centers on using advanced optical techniques for probing and controlling properties of quantum materials, such as topological insulators and high-temperature superconductors. Gedik employs these techniques to search for answers to important problems in condensed matter physics, with a primary focus on understanding the mechanisms behind the unique properties of strongly correlated electron systems. The APS’ Division of Condensed Matter Physics elected Gedik “for the creation of time-resolved techniques to selectively probe dynamics of charge, spin and lattice excitations with unprecedented time, momentum and energy resolutions and for the observation of Floquet-Bloch states in a topological insulator material achieved with novel pump-probe methods.”

Or Hen, the Class of 1956 Career Development Associate Professor of Physics, investigates quantum chromodynamic effects in the nuclear medium and the interplay between partonic and nucleonic degrees of freedom in nuclei. Specifically, Hen utilizes high-energy scattering of electrons, neutrinos, photons, protons, and ions off atomic nuclei to study short-range correlations: temporal fluctuations of high-density, high-momentum, nucleon clusters in nuclei with important implications for nuclear, particle, atomic, and astrophysics. He is also co-leading the development of the ePIC experiment at the Electron-Ion Collider that, once constructed at Brookhaven National Lab, will serve as the United States’ forefront particle collider for the coming decades. The APS Topical Group on Few-Body Systems elected Hen “for using eA and pA hard reaction measurements to advance our knowledge of short-range correlated nucleon pairs in nuclei and their effects on nuclear and nucleon structure.”

Nuno F. Loureiro is a professor in the departments of Nuclear Science and Engineering and of Physics. He is also deputy director of the MIT Plasma Science and Fusion Center. Loureiro’s research focuses on various aspects of magnetized plasma dynamics, such as magnetic reconnection, magnetic field generation and amplification, confinement and transport in fusion plasmas, and turbulence in strongly magnetized, weakly collisional plasmas. New turbulence-related publications by Loureiro’s research group are contributing to the quest to develop nuclear fusion as a practical energy source, and to emerging astrophysical research that delves into the fundamental mechanisms of the universe. The APS’ Division of Plasma Physics elected Loureiro “for elegant, innovative and tenacious engagement in precision studies of nucleon structure, symmetry tests and dark photon searches of physics Beyond the Standard Model with diverse particle beam probes and leading roles in GEM detectors at facilities in USA, Canada, Europe and Japan.”

Jesse Thaler is a theoretical particle physicist in the Center for Theoretical Physics and director of the NSF AI Institute for Artificial Intelligence and Fundamental Interactions. Thaler fuses techniques from quantum field theory and machine learning to address questions in fundamental physics. His current research focuses on maximizing the discovery potential of the Large Hadron Collider through new theoretical frameworks and novel data analysis techniques. Thaler is an expert in jets, which are collimated sprays of particles copiously produced at colliders, and he studies the substructure of jets to enhance the search for new phenomena and illuminate the dynamics of gauge theories. The APS Topical Group on Data Science elected Thaler “for original foundational research contributions, leadership, and mentoring in the area of machine learning for fundamental physics.”

APS honors Anna Frebel, Liang Fu, Nuh Gedik, Or Hen, Nuno Loureiro, and Jesse Thaler for research, applications, teaching, and leadership.
