A groundbreaking new study published in Nature Physics has revealed that geometry influences biofilm growth more than anything else, including the rate at which cells can reproduce. The research shows that the fitness of a biofilm is largely impacted by the contact angle that the biofilm’s edge makes with the substrate.

The team used experiments and simulations to quantify and predict how knit fabric response can be programmed. By establishing a mathematical theory of knitted materials, the researchers hope that knitting — and textiles in general — can be incorporated into more engineering and manufacturing applications.

The Center for Teaching and Learning (CTL) and the Office of Academic Effectiveness (OAE) are thrilled to announce the Spring 2024 Course Instructor Opinion Survey (CIOS) Honor Roll. Faculty members at Georgia Tech who made the Spring 2024 Honor Roll have been celebrated by their students for outstanding teaching and educational impact. 

The award recognizes “honors a scientist or clinician who has made a significant and unique contribution to the field of cardiac pacing and electrophysiology," and recognizes Fenton's groundbreaking research, which uses physics to better understand how the heart functions — or malfunctions, in the case of arrhythmias.

Recent demonstrations of moiré magnetism, featuring exotic phases with noncollinear spin order in the twisted van der Waals (vdW) magnet chromium triiodide CrI3, have highlighted the potential of twist engineering of magnetic (vdW) materials. In this paper, researchers, including School of Physics assistant professors Hailong Wang and Chunhui Du, reported the observation of two distinct magnetic phase transitions with separate critical temperatures within a moiré supercell of small-angle twisted double trilayer CrI3.

An observatory still under construction at the bottom of the Mediterranean Sea has spotted what could be the most energetic neutrino ever detected. Such ultra-high-energy neutrinos — tiny subatomic particles that travel at nearly the speed of light — have been known to exist for only a decade or so, and are thought to be messengers from some of the Universe’s most cataclysmic events, such as growth spurts of supermassive black holes in distant galaxies. “It would be really interesting to see where in the sky the neutrino originated,” says Nepomuk Otte, an associate professor in the School of Physics. Otte is leading a proposed project — with a prototype now being tested in Utah — that would search for Earth-skimming neutrinos by monitoring the atmosphere just above the horizon for flashes of light.

Knitting, the age-old craft of looping and stitching natural fibers into fabrics, is gaining renewed attention for its potential in advanced manufacturing. Beyond creating garments, knitted textiles hold promise for designing wearable electronics and soft robotics – structures that need to move and bend flexibly. A team of physicists from the Georgia Institute of Technology has taken the technical know-how of knitting and added a mathematical foundation to it. Led by Elisabetta Matsumoto, associate professor in the School of Physics, and Krishma Singal, a graduate researcher in Matsumoto’s lab, the team used experiments and simulations to quantify and predict how knitted fabric responses can be programmed.

A group of researchers at the Georgia Institute of Technology have created the world’s first functional semiconductor made from graphene, a development that could lead to advanced electronic devices and quantum computing applications. Seen as the building block of electronic devices, semiconductors are essential for communications, computing, healthcare, military systems, transportation and countless other applications. Semiconductors are typically made from silicon, but this material is reaching its limit in the face of increasingly faster computing and smaller electronic devices, according to the Georgia Tech research team who published their findings in Nature earlier this year. In a drive to find a viable alternative to silicon, Walter de Heer, Regents' Professor in the School of Physics, led a team of researchers based in Atlanta, Georgia and Tianjin, China to produce a graphene semiconductor that is compatible with microelectronics processing methods.

Robotics engineers have worked for decades, using substantial funding, to create robots that can walk or run with the ease of animals. Despite these efforts, today’s robots still cannot match the natural abilities of many animals in terms of endurance, agility, and robustness. Seeking to understand and quantify this disparity, an interdisciplinary team of scientists and engineers from top research institutions, including Dunn Family Associate Professor at the School of Physics and the School of Biological Sciences Simon Sponberg, conducted a comprehensive study to compare various aspects of robotic systems designed for running with their biological counterparts.

In an opinion published in the May 2024 edition of APSNews, School of Physics Professor Andrew Zangwill reflects on the debate on the boundaries of physics and its impact on the discipline. Zangwill states “for more than a century, physicists have been drawing and redrawing the borders around the field, embracing and rejecting subfields along the way.”
