Small robots that have two flapping arms and can’t move around on their own can spontaneously link up and glide together instead. This self-organization may be related to how complex structures arise from simple building blocks in nature. Daniel Goldman, professor in the School of Physics, and his colleagues used small robots called smarticles — short for “smart active particles” — to observe self-organization in the lab.

Black soldier fly larvae devour food waste and other organic matter and are made of 60% protein. But they’re increasingly dying before they reach livestock facilities as animal feed. Researchers, recognizing the culprit is the collective heat generated when the maggots eat in crowded conditions, have found that delivering the right amount of airflow could help solve the overheating issue. A study with those findings, published in Frontiers in Physicsis co-authored by David Hu, professor in the Georgia W. Woodruff School of Mechanical Engineering with a joint appointment in the School of Biological Sciences; and Daniel Goldman, professor in the School of Physics

The Georgia Tech women's volleyball team has a shot to play in their first-ever NCAA Final Four, and third-year School of Physics major Julia Bergmann is a big reason why. The 6' 5'' outside hitter, the ACC's player of the year, made some key kills and serves in the team's Thursday night win over Ohio State. That gives Georgia Tech its second-ever appearance in the Elite 8. Bergmann, whose hometown is Munich, Germany, went to high school in Brusque, Brazil. (Here's the AJC's story on Bergmann being named ACC player of the year, becoming the first Georgia Tech player to win that honor since 2004.)

Ants are among the most industrious creatures on Earth, so it's only fitting that engineers would look to them for inspiration when designing small robots that can collaborate on complex tasks and maneuver through uneven territory. Daniel Goldman, Dunn Family Professor in the School of Physics, was part of a team that created a simple but effective swarm of six-inch "robot" ants that were able to overcome obstacles and terrain individually, and link up to form longer chains when they couldn't accomplish a task alone.

According to a new Georgia Tech study, honeybees have developed a way to convert pollen particles into viscoelastic pellets, allowing them to be efficiently, quickly, and reliably transported to the hive. The study also suggests that insects remove pollen from their bodies at a rate 2-10 times slower than normal grooming rates. College of Sciences researchers who worked on the study include David Hu, professor in the School of Biological Sciences; Peter Yunker, assistant professor, and Gabi Steinbach, postdoctoral researcher, both in the School of Physics. (The study was also reported at Phys.org.)

Astronomers have definitively detected a black hole devouring a neutron star for the first – and second – time. These cataclysmic events created ripples in space-time called gravitational waves that travelled more than 900 million light years to reach detectors on Earth. Many astronomers contributed to the findings, published in the Astrophysical Journal Letters, including Bhavesh Khamesra, a graduate student in the School of Physics. The study was also covered at Phys.org

Biofilms 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.

Postdoctoral researcher Aniruddha Bhattacharya and School of Physics Professor Chandra Raman have introduced a novel way to generate entanglement between photons – an essential step in building scalable quantum computers that use photons as quantum bits (qubits). Their research, published in Physical Review Letters, leverages a mathematical concept called non-Abelian quantum holonomy to entangle photons in a deterministic way without relying on strong nonlinear interactions or irrevocably probabilistic quantum measurements.

Peter Yunker, associate professor in the School of Physics, reflects on the results of new experiments which show that cells pack in increasingly well-ordered patterns as the relative sizes of their nuclei grow.

“This research is a beautiful example of how the physics of packing is so important in biological systems,” states Yunker. He says the researchers introduce the idea that cell packing can be controlled by the relative size of the nucleus, which “is an accessible control parameter that may play important roles during development and could be used in bioengineering.”

School of Physics Professor Ignacio Taboada provided brief commentary on KM3NeT, a new underwater neutrino experiment that has detected what appears to be the highest-energy cosmic neutrino observed to date.

“This is clearly an interesting event. It is also very unusual,” said Taboada, spokesperson for the IceCube experiment in Antarctica. IceCube, which has a similar detector-array design as KM3NeT but is encased in ice rather than water, has detected neutrinos with energies as high as 10 PeV, but nothing in 100 PeV range. “IceCube has worked for 14 years, so it’s weird that we don’t see the same thing,” Taboada said. Taboada is not involved in the KM3Net experiment. 

The KM3NeT team is aware of this weirdness. They compared the KM3-230213A event to upper limits on the neutrino flux given by IceCube and the Pierre Auger cosmic-ray experiment in Argentina. Taking those limits as given, they found that there was a 1% chance of detecting a 220-PeV neutrino during KM3NeT’s preliminary (287-day) measurement campaign.

Despite the fact that Antarctica is extraordinarily difficult to get to, astronomers love it and have chosen it as the location for the IceCube Neutrino Observatory. What could possibly make such a remote location so desirable for space science that it’s worth all that trouble? 

In this article, scientists including Georgia Tech's Brandon Pries from the School of Physics explain why the South Pole is such a hotspot for astronomers. The answer? At the South Pole, you can best view neutrons and neutrinos in space. 

Pries compares the benefits of the South Pole to the North Pole. “The North Pole is more difficult because ice coverage there fluctuates,” explains Pries. “There is a foundation of bedrock underneath Antarctica that serves as a solid base for the IceCube instruments.” This bedrock is also why Antarctica is home to the South Pole Telescope, a radio observatory that helped take the first ever photo of a black hole.
