This paper refined the current understanding of how fish navigate their underwater world could provide insights that can be applied to underwater robots, according to Science News. Robots are often designed with separate apparatus for movement and sensing, but, as Simon Sponberg, a biophysicist at the Georgia Tech, tells Science News, “biology puts sensors on everything.”

Luckily, a team of researchers from Georgia Tech's Center for Relativistic Astrophysics recently conducted simulations that show what the formation of the first stars looked like. The study that describes their findings, published in the Monthly Notices of the Royal Astronomical Society, was led by Gen Chiaki and John Wise – a post-doctoral researcher and associate professor from the CfRA (respectively).

Physicists and biologists challenge a prevailing evolutionary theory that single-celled organisms can only evolve to become multicellular life forms if doing so increases their overall productivity.

“Rather than each cell producing what it needs, specialised cells need to be able to trade with each other. Previous work suggests that this only happens as long as the overall group’s productivity keeps increasing,” explains lead author David Yanni, PhD student at Georgia Institute of Technology, Atlanta, US.

“We can’t see the very first generations of stars,” said study co-author John Wise, an associate professor at the Center for Relativistic Astrophysics at Georgia Tech. “Therefore, it’s important to actually look at these living fossils from the early universe, because they have the fingerprints of the first stars all over them through the chemicals that were produced in the supernova from the first stars.”

Far outside our solar system and out past the distant reachers of our galaxy—in the vast nothingness of space—the distance between gas and dust particles grows, limiting their ability to transfer heat. There may be pockets of the universe where temperatures drop to 1 Kelvin above absolute zero, astronomer Jim Sowell of the Georgia Institute of Technology notes, but so far, the closest measurement to absolute zero has only been observed in laboratories here on Earth.

It was a long and storied path for Dr. James “Jim” Sowell to get the 20-inch, Italian Officina Stellare telescope installed on the roof of the Howey Physics Building. But he succeeded, and today during Public Nights, young stargazers not only have access to Georgia Tech’s Observatory, they’re also learning about the solar system, stars, galaxies, and the universe, as well as astro-particle, electromagnetic, gravitational, and stellar astrophysics.

School of Physics Spring Colloquium Series- Dr. Subir Sachdev

Speaker: Dr. Subir Sachdev Host: Zhu-Xi Luo Title: Detecting a quantum spin liquid in the cuprate superconductors Abstract: Soon after the discovery of the cuprate high-temperature superconductors, P. W. Anderson presciently suggested in 1987 that their physics is connected to highly entangled many-body states now known as quantum spin liquids. However, the development of this idea over subsequent decades encountered significant tensions with experimental observations. I address these difficulties using the fractionalized Fermi liquid (FL*) state, proposed in 2002, which describes the doping of a quantum spin liquid with electron-like quasiparticles. Recent angle-dependent magnetoresistance measurements in lightly hole-doped cuprates are consistent with key predictions of the FL* theory. The non-symmetry-breaking quantum phase transition between the FL* state and a conventional Fermi liquid, in the presence of impurities, can be described by a two-spatial-dimensional extension of the Sachdev–Ye–Kitaev (SYK) model. This framework is then applied to the strange-metal regime at intermediate temperatures and dopings. I will also briefly mention how the SYK model has led to recent progress in understanding the density of quantum states of charged black holes. Bio: Subir Sachdev is Herchel Smith Professor of Physics at Harvard University. He has been elected to national academies of science in India and the US, and the Royal Society in the U.K. He is a recipient of several awards, including the Dirac Medal from the International Centre for Theoretical Physics, and the Lars Onsager Prize from the American Physical Society. Sachdev has made extensive contributions to the theory of the diverse varieties of states of quantum matter, and of their behavior near quantum phase transitions.

In an article published in Physics MagazineSchool 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.

Researchers 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.

A similar story also appeared at The Hindu.

Other 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.

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.”
