The Department of Physics at Illinois welcomes an extraordinary set of ten new faculty members this year. Eight of them have arrived on campus and have begun setting up their labs and settling into life in Champaign-Urbana. Two more faculty are set to arrive in January. We will feature each of them here over the next couple of weeks. Check back regularly to learn more about the exciting work these new faculty members are doing.

Professor Jaki Noronha-Hostler

Jaki Noronha-Hostler is a nuclear physicist. In her research, she does simulations of the most perfect fluid we know of–quark-gluon plasma–moving at the speed of light, and then compares the simulations directly to experimental data. This type of matter is believed to have existed 10-6 seconds after the big bang, so to study it, nuclear experimentalists create billions of “little bangs” in the laboratory. The goal of her current research is to find the location a critical point at which separates the cross-over phase transition (between a quark gluon plasma and hadrons) from a first order phase transition. This research has implications for several areas of physics, including neutron stars, which may contain a quark-gluon plasma at their core. Jaki says, “If we see a critical point, then there is a first order phase transition that could affect the dynamics of neutron star mergers.” Her work also pushes the boundaries of statistics, because new statistical tools have to be developed to analyze the data from the large number of simulations required for this research.

Albert Einstein was right again. More than 100 years ago, his calculations suggested that when too much energy or matter is concentrated in one place, it will collapse in on itself and turn into a dark vortex of nothingness. Physicists found evidence to support Einstein’s black hole concept, but they’d never observed one directly. In 2017, 200-plus scientists affiliated with more than 60 institutions set out to change that, using eight global radio observatories to chart the sky for 10 days. In April they released their findings, which included an image of a dark circle surrounded by a fiery doughnut (the galaxy Messier 87), 55 million light years away and 6.5 billion times more massive than our sun. “We have seen what we thought was unseeable,” said Shep Doeleman, leader of what came to be known as the Event Horizon Telescope team. The team’s name refers to the edge of a black hole, the point beyond which light and matter cannot escape. In some ways, the first picture of a black hole is also the first picture of nothing.

Institute for Condensed Matter Theory in the Department of Physics at the University of Illinois at Urbana-Champaign has recently received a five-year grant of over $1 million from the Gordon and Betty Moore Foundation. The grant is part of the Gordon and Betty Moore Foundation’s Emergent Phenomena in Quantum Systems (EPiQS) Initiative, which strives to catalyze major discoveries in the field of quantum materials—solids and engineered structures characterized by novel quantum phases of matter and exotic cooperative behaviors of electrons. This is the second 5-year EPiQS grant awarded to the ICMT by the Moore Foundation. The two awards establish an EPiQS Theory Center at the Institute for Condensed Matter Theory.

  • Accessibility

University of Illinois at Urbana-Champaign physics graduate student Colin Lualdi quickly realized he was venturing into uncharted territory when he arrived at Illinois Physics at the start of Fall 2017. Deaf since birth and a native speaker of American Sign Language (ASL), Lualdi was now among a very small group worldwide of Deaf individuals working in physics. The exhilaration of performing cutting-edge research was accompanied by a sobering discovery: the lack of a common language model for effective scientific discourse in ASL was going to be a far greater challenge than he’d anticipated. Lualdi has embraced his own accessibility challenges as an opportunity to address a pressing need in the broader Deaf community. He has teamed up with colleagues at other research institutions to develop a robust and shared framework for scientific discourse in ASL. Specifically, Colin has been working with ASL Clear and ASLCORE, two national scientific sign language initiatives that are making good progress.
