Promoting new research directions in the physical and mathematical sciences.
Professor Cheng Chin has received the ’21–’22 Marian and Stuart Rice Research Award, a Divisional honor that provides $100,000 for intellectually exciting and innovative research ventures that enable new research directions.
Chin joined the University of Chicago in 2005 and has been a full professor in the Department of Physics, the Enrico Fermi Institute, and the James Franck Institute since 2012. He is a pioneer in using ultracold atoms to study the quantum phenomena that underlie the behavior of other particles in the universe.
“I am very excited about this generous support from the PSD, and especially from Stuart Rice,” he said. “The fund will enable a brand new research line into molecular quantum matter, on which my students and I are very excited to begin.”
The Marian and Stuart Rice Research Award was established by the family of Stuart Alan Rice, the Frank P. Hixon Distinguished Service Professor Emeritus in Chemistry and former chairman of the Department of Chemistry and dean of the Physical Sciences (1981-1995). It is awarded annually to promote new directions of research in the physical and mathematical sciences at the University of Chicago.

Opening up new fields in quantum chemistry and technology.
Researchers have big ideas for the potential of quantum technology, from unhackable networks to earthquake sensors. But all these things depend on a major technological feat: being able to build and control systems of quantum particles, which are among the smallest objects in the universe.
That goal is now a step closer with the publication of a new method by University of Chicago scientists. Published April 28 in Nature, the paper shows how to bring multiple molecules at once into a single quantum state—one of the most important goals in quantum physics.
"People have been trying to do this for decades, so we’re very excited,” said senior author Cheng Chin, a Professor of Physics and the James Franck Instiute who said he has wanted to achieve this goal since he was a graduate student in the 1990s. “I hope this can open new fields in many-body quantum chemistry. There’s evidence that there are a lot of discoveries waiting out there.”

$2 Million award recognizes curiosity-driven basic research in chemistry and physics.
The Brown Science Foundation announced March 8 that it has chosen University of Chicago Prof. William Irvine for its inaugural Brown Investigator Award. The award, which recognizes curiosity-driven basic research in chemistry and physics, supports the investigators’ research with $2 million over five years to their respective universities. Irvine, who researches fundamental problems in fluid dynamics and condensed matter, is one of two scientists chosen, along with David Hsieh of Caltech.
“Even among a strong group of candidates, Hsieh and Irvine stood out for their scientific vision and willingness to take risk,” said Marc Kastner, senior science advisor for the Science Philanthropy Alliance and chairman of the foundation’s scientific advisory board, which selected the winners. “They’re clear examples of America’s reservoir of mid-career scientists with the proven track record and restless minds needed to advance daring ideas.”
The Brown Science Foundation, a member of the Science Philanthropy Alliance, was established in 1992 by Ross M. Brown. The foundation announced its invitation-only Brown Investigator Award program in 2020 with plans to make eight awards annually by 2025. The program supports the often-overlooked resource of mid-career physics and chemistry researchers in the U.S. According to its website, the foundation is “dedicated to the belief that scientific discovery is a driving force in the improvement of the human condition.”

Discovery addresses problem of generating and moving energy efficiently.
Three scientists from the Maziotti group in the JFI have run the numbers, and they believe there may be a way to make a material that could conduct both electricity and energy with 100% efficiency—never losing any to heat or friction.
The breakthrough, published Feb. 18 in Physical Review B, suggests a framework for an entirely new type of matter, which could have very useful technological applications in the real world. Though the prediction is based on theory, efforts are underway to test it experimentally.
“We started out trying to answer a really basic question, to see if it was even possible—we thought these two properties might be incompatible in one material,” said co-author and research adviser David Mazziotti, a professor of chemistry and the James Franck Institute and an expert in molecular electronic structure. “But to our surprise, we found the two states actually become entangled at a quantum level, and so reinforce each other.”
Graduate student LeeAnn Sager began to wonder how the two states could be generated in the same material. Mazziotti’s group specializes in exploring the properties and structures of materials and chemicals using computation, so she began plugging different combinations into a computer model. “We scanned through many possibilities, and then to our surprise, found a region where both states could exist together,” she said.
“Being able to combine superconductivity and exciton condensates would be amazing for lots of applications—electronics, spintronics, quantum computing,” said Shiva Safaei, a postdoctoral researcher and the third author on the paper. “Though this is a first step, it looks extremely promising.”

Breakthrough creates tough material able to stretch, heal and defend itself.
While eating takeout one day, James Franck Institute scientists Bozhi Tian and Yin Fang started thinking about the noodles—specifically, their elasticity. A specialty of Xi’an, Tian’s hometown in China, is wheat noodles stretched by hand until they become chewy—strong and elastic. Why, the two materials scientists wondered, didn’t they get thin and weak instead?
They started experimenting, ordering pounds and pounds of noodles from the restaurant. “They got very suspicious,” Fang said. “I think they thought we wanted to steal their secrets to open a rival restaurant.”
But what they were preparing was a recipe for synthetic tissue—that could much more closely mimic biological skin and tissue than existing technology.
“It turns out that granules of common starch can be the missing ingredient for a composite that mimics many of the properties of tissue,” said Fang, a UChicago postdoctoral researcher and lead author of a new paper published Jan. 29 in the journal Matter. “We think this could fundamentally change the way we can make tissue-like materials.”
The breakthrough allows the synthetic tissue to stretch in multiple directions but to heal and defend itself by reorganizing its internal structures —which is how human skin protects itself. The discovery could one day lead to applications from soft robotics and medical implants to sustainable food packaging and biofiltration.
