Although it’s understood that water ice exists below the lunar regolith (broken rock and dust), scientists don’t yet know whether surface ice frost covers the floors inside cold, dark craters. NASA is sending Lunar Flashlight, a small satellite (or SmallSat) no larger than a briefcase to find out. The mission, which will use lasers to shed light on those dark craters, will launch in mid-November aboard a SpaceX Falcon 9 rocket. Lunar Flashlight will be operated by Georgia Tech with its data set to be studied by the REVEALS (Radiation Effects on Volatiles and Exploration of Asteroids and Lunar Surfaces) Lab, a collaborative effort involving students and researchers from the Colleges of Sciences and Engineering. Thomas Orlando, professor in the School of Chemistry and Biochemistry, and an adjunct professor in the School of Physics, is the principal investigator with REVEALS.
NASA’s Lunar Flashlight Ready to Search for Water Ice on the Moon 2022-10-31T00:00:00-04:00A recently discovered, never-before-seen phenomenon in a type of quantum material could be explained by a series of buzzing, bee-like “loop-currents.” The discovery from physicists at the University of Colorado Boulder (CU Boulder) and Georgia Tech may one day help engineers develop new types of devices, such as quantum sensors, or the quantum equivalent of computer memory storage devices. The Georgia Tech researchers from the School of Physics who co-authored the study are Itamar Kimchi, assistant professor, and Sami Hakani, graduate student.

Able Channel Announces One Hour Television Special "Together We Are Able" 2022-10-04T00:00:00-04:00Astronauts could return to the moon in a few years, and if they do, they might be wearing spacesuits designed with the help of Thom Orlando, professor in the School of Chemistry and Biochemistry, and the School of Physics. Orlando, who is also a co-founder of Georgia Tech's Center for Space Technology and Research, spoke with GPB's Peter Biello about the science of spacesuit design.
Georgia Tech professor helps design NASA’s latest generation spacesuits 2022-09-27T00:00:00-04:00In a physics lab in Amsterdam, there’s a wheel that can spontaneously roll uphill by wiggling. This “odd wheel” looks simple: just six small motors linked together by plastic arms and rubber bands to form a ring about 6 inches in diameter. When the motors are powered on, it starts writhing, executing complicated squashing and stretching motions and occasionally flinging itself into the air, all the while slowly making its way up a bumpy foam ramp. The odd wheel’s unorthodox mode of travel exemplifies a recent trend: Physicists are finding ways to get useful collective behavior to spontaneously emerge in robots assembled from simple parts that obey simple rules. Daniel Goldman, Dunn Family Professor in the School of Physics (who did not work on the odd wheel study), uses the term "robophysics" to describe this latest trend in robotics.
A Wheel Made of ‘Odd Matter’ Spontaneously Rolls Uphill 2022-09-25T00:00:00-04:00Electrical signals tell the heart to contract, but when the signals form spiral waves, they can lead to dangerous cardiac events like tachycardia and fibrillation. Researchers at Georgia Tech and clinicians at Emory University School of Medicine are bringing a new understanding to these complicated conditions with the first high-resolution visualizations of stable spiral waves in human ventricles. The Georgia Tech School of Physics researchers are Flavio Fenton, professor, and IIija Uzelac, research scientist.
Researchers map rotating spiral waves in live human hearts 2022-09-07T00:00:00-04:00NASA is preparing to enter a new space age from Florida's space coast, and a scientist in Georgia is helping newly tapped Artemis astronauts step onto the moon with next-generation suits. Thom Orlando, professor in the School of Chemistry and Biochemistry, and the School of Physics, is a co-founder of the Center for Space Technology and Research. Orlando has been working with NASA to design the space suits that future astronauts will wear as they walk on the lunar surface.
How this Georgia Tech professor is fashioning the next generation of NASA space suits 2022-09-03T00:00:00-04:00After years of planning and two Covid-induced delays, the TRACER (TRacking Aerosol Convection interactions ExpeRiment) field campaign began last fall in the Houston, Texas, region, collecting data on clouds, aerosols, precipitation, meteorology, and radiation 24 hours a day, seven days a week. A four-month intensive operational period began June 1, bringing many more instruments and detailed measurements to the campaign. This allowed a group of undergraduate and high school interns at Brookhaven National Laboratory to gain firsthand experience analyzing real atmospheric data and contribute to the science coming from TRACER. One of those undergraduate interns is Emily Melvin of the School of Physics, who blogs that she was "allowed to practice my forecasting skills and explore some of the resources available to meteorologists."
TRACER Talk: Student Interns Contribute to Early Research Efforts 2022-08-31T00:00:00-04:00Turbulence plays a key role in our daily lives, making for bumpy plane rides, affecting weather and climate, limiting the fuel efficiency of the cars we drive, and impacting clean energy technologies. Yet, scientists and engineers have puzzled at ways to predict and alter turbulent fluid flows, and it has long remained one of the most challenging problems in science and engineering. Now, physicists from the Georgia Institute of Technology have demonstrated — numerically and experimentally — that turbulence can be understood and quantified with the help of a relatively small set of special solutions to the governing equations of fluid dynamics that can be precomputed for a particular geometry, once and for all. The research by Roman Grigoriev and Michael Schatz, professors in the School of Physics, was also covered in ScienceDaily.
Physicists uncover new dynamical framework for turbulence 2022-08-29T00:00:00-04:00Scientists at Georgia Tech and Clark University have developed robotic lizards in a collaboration combining robotics, math, biology, and artificial intelligence. The robots helped solve an evolutionary puzzle and could be the first step towards a new generation of wiggling robots. The team used artificial intelligence to study the movement of various lizard species. “We were interested in why and how these intermediate lizards use their bodies and limbs to move around in different terrestrial environments,” says one of the study’s authors, Daniel Goldman, Dunn Family Professor in the School of Physics. “This is a fundamental question in locomotion biology and can inspire more capable wiggling robots.” Other School of Physics scientists involved in the research include Ph.D. students Baxi Chong and Tianyu Wang, and Eva Erickson (B.S. PHYS '22).
Meet the Lizard Robot That Could Save Your Life 2022-08-01T00:00:00-04:00Elisabetta Matsumoto, an assistant professor in the School of Physics, is featured in a documentary directed by Shruti Mandhani, a research fellow for the Engineering and Physical Sciences Research Council in the United Kingdom, and a Ph.D. student at Sheffield Hallam University. The documentary focuses on imposter syndrome, a psychological condition in which individuals doubt their skills and abilities, and fear being discovered as frauds. Mandhani interviewed other women in STEM (science, technology, mathematics, and engineering) disciplines for the documentary, which is shortlisted for the Bristol Science Film Festival in August.
Meeting my Role Models: An Insight into Imposter Syndrome 2022-07-19T00:00:00-04:00Small 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.

Experts in the News
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.
Physics World 2025-04-09T00:00:00-04:00Peter 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.”
Physics Magazine 2025-03-21T00:00:00-04:00School 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.

Researchers from the University of Georgia and Georgia Tech demonstrated that space weathering alterations of the surface of lunar samples at the nanoscale may provide a mechanism to distinguish lunar samples of variable surface exposure age.
Nature Scientific Reports 2025-01-02T00:00:00-05:00Despite 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.
