These cycles are the periodic variations that influence a planet's orbital properties. This, in turn, controls how much sunlight the planet receives over time and thus plays an important role in determining the planet's climate and habitability. A new study, inspired by Milankovitch cycles, has attempted to investigate how orbital changes may affect the climate of exoplanets. They investigated orbit variations in compact multiplanet systems for this purpose. Gongjie Li, assistant professor in the School of Physics, was a co-author of the study.

Interesting Engineering 2023-03-31T00:00:00-04:00A tiny NASA moon probe continues to battle thruster issues as it attempts to reach its destination, but there's still time left to make a fix. Lunar Flashlight launched in December 2022 on a quest to seek lunar ice. But on the way to the moon, the cubesat experienced thruster glitches on its mission to test a new "green" propellant. NASA officials downgraded its mission from orbiting to lunar flybys weeks ago. NASA and mission partners at the Georgia Institute of Technology emphasize the lunar flybys will still be valuable, as they will bring the Cubesat by the south pole of the moon where NASA's Artemis program aims to land astronauts as soon as 2025. A team from the Guggenheim School of Aerospace Engineering runs mission control activities, and Georgia Tech's REVEALS (Radiation Effect on Volatiles and Exploration of Asteroids and Lunar Surfaces) team, led by principal investigator Thomas Orlando, professor in the School of Chemistry and Biochemistry and adjunct professor in the School of Physics, will study any data collected on lunar ice.

The closeups and slow-motion photography are necessary to show the role toad saliva plays in snatching crickets, worms, and other prey in the blink of an eye. Thanks to research from the team of David Hu, professor in the School of Biological Sciences with an adjunct appointment in the School of Physics, science learned that a toad’s saliva starts off thick and sticky. But when the saliva hits prey at a high speed, it thins out dramatically, pouring into every nook and cranny the tongue touches. And then, it becomes sticky again, drawing that meal down the hatch.
KQED 2023-03-28T00:00:00-04:00Chia seeds sprouted in trays have experimentally confirmed a mathematical model proposed by computer scientist and polymath Alan Turing decades ago. The model describes how patterns might emerge in nature, such as desert vegetation, leopard spots and zebra stripes. But proving that Turing’s model explains patterns in the real world has been challenging. It could be that the idea is a mathematical just-so story that happens to produce similar shapes in a computer, says Flavio Fenton, professor in the School of Physics. Brendan D'Aquino, a Northeastern University computer science undergraduate student who studied in Fenton's lab in the summer of 2022, described his Turing-based experiment at the recent American Physical Society March meeting.

Science News 2023-03-26T00:00:00-04:00Black holes remain one of the great mysteries of the universe. Another enigma? Dark energy. Little is known about this concept, aside from the belief that dark energy accelerates the expansion of the universe. There’s a new theory that brings together black holes and dark energy into one mind-bending solution: research led by the University of Hawai’i at Manoa posits that dark energy could actually come from supermassive black holes at the center of galaxies. Feryal Özel, professor and chair of the School of Physics, and a founding member of the Event Horizon Telescope project that has captured images of black holes, joined host Ira Flatow to talk about the new development.
WNYC Science Friday 2023-03-10T00:00:00-05:00A collaboration of physicists working at different institutes in the U.S. — including two at Georgia Tech — has discovered a new quantum state in an alloy made of magnesium, silicon, and tellurium, a press release said. The finding could result in applications in quantum computing, such as building sensors and communication systems. The alloy is a crystalline structure denoted as Mn3Si2Te6 and consists of octagonal cells placed in a honeycomb-like arrangement when viewed from above. Though, when viewed from the side, it consists of stacked sheets. Two researchers in the School of Physics, assistant professor Itamar Kimchi and graduate student Sami Hakani, worked on the study announcing the new quantum state.
Interesting Engineering 2023-02-27T00:00:00-05:00The headline for this article refers to a Swedish technology startup company using origami-inspired techniques for its 3D printing services. But it also mentions Georgia Tech winning a Department of Defense grant for a project titled Programming Multistable Origami and Kirigami Structures via Topological Design, which investigated how concepts from the art of paper folding can be combined with 3D printing to create lightweight, flexible structures that can change shape. Zeb Rocklin, an assistant professor in the School of Physics, was part of the project team.

But what cannot be disputed is its incredible influence in modern engineering. While styles of origami can be incredibly diverse, the art is rooted in mathematical principles that make it applicable to science and industry. This story in E&T mentions scientists at Georgia Tech exploring origami, kirigami (where paper is cut as well as folded) and specific folding techniques for building everything from furniture to bridges. One of those scientists is D. Zeb Rocklin, assistant professor in the School of Physics.

A startup called Istari, backed by Eric Schmidt, the former CEO of Google and chair of Alphabet, reckons some of that work can be done more effectively in the metaverse. Ishtari uses machine learning to virtually assemble and test war machines from computer models of individual components, such as the chassis and engines, that are usually marooned on separate digital drawing boards. Will Roper, B.S. and M.S. PHYS, and a former assistant secretary of the Air Force, is founder and CEO of Ishtari.
Wired 2023-02-13T00:00:00-05:00Astrobites, a daily astrophysical literature journal written by graduate students in astronomy since 2010, features a guest column written by two Ph.D. students extolling the virtues of community college. One of the authors is School of Physics alumna Kiersten Boley, B.S PHYS 2019, now seeking a Ph.D. in astronomy from Ohio State University. Boley writes that she didn't want to become a physicist until she attended community college, where her professor in introductory physics "sparked my love of science." Boley credits that with helping her thrive at Georgia Tech.
Breaking the Stigma around Community College 2023-02-12T00:00:00-05:00A pressing quest in the field of nanoelectronics is the search for a material that could replace silicon. Graphene has seemed promising for decades. But, its potential faltered along the way, due to damaging processing methods and the lack of a new electronics paradigm to embrace it. With silicon nearly maxed out in its ability to accommodate faster computing, the next big nanoelectronics platform is needed now more than ever. Walter de Heer, Regents’ Professor in the School of Physics at the Georgia Institute of Technology, has taken a critical step forward in making the case for a successor to silicon. De Heer and his collaborators, including Claire Berger, fellow School of Physics professor, developed a new nanoelectronics platform based on graphene — a single sheet of carbon atoms.

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.
