The latest discovery from Georgia Tech physicists may seem like something straight out of Black Mirror. But don't worry, it's not that sinister. School of Physics' Dan Goldman worked with School of Computer Science's Dana Randall and doctoral student William Savoie to develop an algorithm that orders simple robots to "swarm," or move in complex ways as a group. Imagine the birth of the supervillain Sandman in Spider-Man 3, from loose grains of sand skittering across the desert and then congealing into the shape of a human. The possiblities for these "smarticles" are endless. This story has been reproduced in Scientific American.
Metz Mayor 2018-02-14T00:00:00-05:00You won’t feel it happen, but the kilogram, used to measure the mass of electrons, galaxies, and everything in between, is about to be transformed. The General Conference on Weights and Measures is set to meet to redefine the kilogram in terms of a physical constant, Planck's constant. Ronald Fox of the School of Physics, an early advocate of redefining the kilogram, is very pleased. Commenting on the story, he mentions the LIGO experiment to detect gravitational waves, in which Georgia Tech researchers participated. "The unit of mass is very important because you're looking at a very, very delicate effect."
recycling event 2018-02-06T00:00:00-05:00Look up at the winter sky on a clear night. The brilliance of the stars is breathtaking. James Sowell, an astronomer in the School of Physics, weighs in on why stargazing is so beautiful in the winter. "There are more brighter stars in the quarter of the sky that we call the winter sky. Plus, cold air holds less moisture than the warmer summer air, making the nights clearer. So, faint stars that may go unseen during the summer nights may be more visible," Sowell says. So take Sowell's advice, grab your tent, and get out there! Or just come to Public Nights at the Georgia Tech Observatory. The next one is on Feb 22.
materials for energy harvesting 2018-01-23T00:00:00-05:00School of Physics researchers Paul Goldbart, Benjamin Loewe, and Anton Souslov have made a breakthrough in fluid dynamics. They've derived hydrodynamic equations describing active fluids, something that had proven very difficult to do in the past. Their research was published in the New Journal of Physics. Loewe was a doctoral student and Souslov was a postdoctoral research associate in Goldbart's research group in the School of Physics. Goldbart is also College of Sciences Dean and Sutherland Chair .
Experimental Flights class 2018-01-22T00:00:00-05:00Georgia Public Broadcasting radio host Celeste Headlee replays her 2015 interview with Patricia Yang, a doctoral student and co-winner of an Ig Nobel Award, an honor presented by Improbable Research given to science projects that "make you laugh, then make you think." Yang's award was for a study on animal urination, which involved monitoring and recording the bladder-emptying habits of 32 different mammals at Zoo Atlanta. Yang worked on the study with David Hu, an associate professor in the George W. Woodruff School of Mechanical Engineering and the School of Biological Sciences, with an adjunct appointment in the School of Physics.
Ilker Çatak 2018-01-10T00:00:00-05:00A Georgia Tech honors graduate who was both a Rhodes and Truman Scholar may have a chance to impact the purchase of new technologies for the Air Force. William Roper, currently founding director of the Pentagon's Strategic Capabilities Office, is President Trump's nominee to be assistant secretary of the Air Force for acquisitions. Roper, who has argued that the Defense Department should use more commercial software, graduated summa cum laude with a B.S. from the School of Physics in 2001. He earned his M.S. in physics from Tech in 2002, also summa cum laude. Roper has a Ph.D. in mathematics from the University of Oxford.
digital divide 2018-01-03T00:00:00-05:00Yes, last year's detection of neutron stars colliding was indeed "kind of a big deal," especially here at Georgia Tech. Seventeen of our faculty members, researchers, and students were part of the international Laser Interferometer Gravitational-Wave Observatory team that detected the first-ever observation of a kilonova, or neutron star mashup. LIGO Deputy Spokesperson Laura Cadonati, quoted in this story, is also a professor in the School of Physics. (This Newsweek story is essentially a recap of a Science magazine item that named LIGO's discovery as Breakthrough of the Year.)
Elizabeth Kornegay 2017-12-22T00:00:00-05:00The school year started with a total solar eclipse that captivated thousands on Tech Green. For some schools, that would be enough to qualify for a memorable year. But this is Georgia Tech, and events before and after Aug. 21's celestial happening also put a spotlight on the Institute. In addition to the eclipse watch party on campus, the College of Science's contributions to this list of top Tech news stories for the year includes gravitational waves from neutron star collisions, golden nanorods used to fight cancer, robots for exploring frozen moons of Jupiter, and a Rhodes Scholar in the School of Chemistry and Biochemistry.

Experts in the News
Research led by Georgia Tech physicist Itamar Kolvin has found that the presence of small imperfections or heterogeneities in materials can have a dual effect on their strength and resilience. While heterogeneities were historically believed to make materials stronger by creating an obstacle course for cracks, the new study shows that in some complex materials, heterogeneities can actually accelerate crack propagation and weaken the overall structure. The findings have implications for how engineers design and reinforce materials to optimize their toughness.
Atlanta Today 2026-02-27T00:00:00-05:00Assistant Professor Zhu-Xi Luo and Ph.D. student Yi-Lin Tsao from Georgia Institute of Technology's School of Physics have demonstrated a novel mechanism for stabilising physical phases vulnerable to topological defects. Their work addresses a fundamental problem in condensed matter physics: the destabilisation of phases like superfluids by thermally-induced defects such as anyons and vortices.
Quantum Zeitgeist 2026-02-25T00:00:00-05:00In an article published in Physics Magazine, School of Physics Ph.D. student Jingcheng Zhou and Assistant Professor Chunhui (Rita) Du review efforts to optimize diamond-based quantum sensing. According to Zhou and Du, the approach used in two recent studies broadens the potential applications of nitrogen-vacancy center sensors for probing quantum phenomena, enabling measurements of nonlocal properties (such as spatial and temporal correlations) that are relevant to condensed-matter physics and materials science.
Physics Magazine 2025-07-14T00:00:00-04:00Researchers at the Georgia Institute of Technology and India's National Center for Biological Sciences have found that yeast clusters, when grown beyond a certain size, spontaneously generate fluid flows powerful enough to ferry nutrients deep into their interior.
In the study, "Metabolically driven flows enable exponential growth in macroscopic multicellular yeast," published in Science Advances, the research team — which included Georgia Tech Ph.D. scholar Emma Bingham, Research Scientist G. Ozan Bozdag, Associate Professor William C. Ratcliff, and Associate Professor Peter Yunker — used experimental evolution to determine whether non-genetic physical processes can enable nutrient transport in multicellular yeast lacking evolved transport adaptations.

Phys.org 2025-06-24T00:00:00-04:00Other planets, dwarf planets and moons in our solar system have seasonal cycles — and they can look wildly different from the ones we experience on Earth, experts told Live Science.
To understand how other planets have seasons, we can look at what drives seasonal changes on our planet. "The Earth has its four seasons because of the spin axis tilt," Gongjie Li, associate professor in the School of Physics, told Live Science. This means that our planet rotates at a slight angle of around 23.5 degrees.
"On Earth, we're very lucky, this spin axis is quite stable," Li said. Due to this, we've had relatively stable seasonal cycles that have persisted for millennia, although the broader climate sometimes shifts as the entire orbit of Earth drifts further or closer from the sun.
Such stability has likely helped life as we know it develop here, Li said. Scientists like her are now studying planetary conditions and seasonal changes on exoplanets to see whether life could exist in faroff worlds. For now, it seems as though the mild seasonal changes and stable spin tilts on Earth are unique.
Live Science 2025-05-05T00:00:00-04:00Biofilms have emergent properties: traits that appear only when a system of individual items interacts. It was this emergence that attracted School of Physics Associate Professor Peter Yunker to the microbial structures. Trained in soft matter physics — the study of materials that can be structurally altered — he is interested in understanding how the interactions between individual bacteria result in the higher-order structure of a biofilm
Recently, in his lab at the Georgia Institute of Technology, Yunker and his team created detailed topographical maps of the three-dimensional surface of a growing biofilm. These measurements allowed them to study how a biofilm’s shape emerges from millions of infinitesimal interactions among component bacteria and their environment. In 2024 in Nature Physics, they described the biophysical laws that control the complex aggregation of bacterial cells.
The work is important, Yunker said, not only because it can help explain the staggering diversity of one of the planet’s most common life forms, but also because it may evoke life’s first, hesitant steps toward multicellularity.
