For the first time we know the shape of electrons, thanks to a breakthrough in quantum physics
A discovery in electron behavior
The research was led by MIT physicist Riccardo Comin, along with a team from other institutions. Their findings could change the way we understand and control electrons, both in theory and in technology. In other words, they’re not just reshaping science—they’re literally reshaping how we see electrons!
“We’ve essentially created a blueprint for unlocking completely new information that was previously out of reach,” Comin explained. His colleague and co-author, Mingu Kang, conducted much of the research while at MIT before continuing his work at Cornell University.
How scientists mapped the shape of an electron
Physicists have spent decades trying to crack the mystery of electrons, but these tiny particles refuse to make things easy. Instead of behaving like simple dots moving through space, they also act like waves, meaning they don’t always follow the usual rules of physics.
Think of electrons like ripples in a pond—sometimes their patterns are smooth and predictable, and other times they twist and tangle in ways that are tough to track. Mapping out these wave patterns is no small feat, especially since they exist in dimensions beyond what we can see.
What ARPES reveals about electrons
To capture these details, the research team turned to angle-resolved photoemission spectroscopy (ARPES)—a high-tech method that blasts electrons with light and watches how they react. This approach let them zoom in on electrons like never before, uncovering shapes and behaviors that had been invisible until now.
Normally, when discussing electrons, the focus is on energy or velocity—concepts most people are familiar with. Geometry, however, refers to the patterns and structures that electron waves adopt when they settle into a solid. In other words, it’s not just about how fast they move, but also about how they’re shaped while doing it.
Quantum geometry plays a huge role in how electrons interact, form pairs, and sometimes behave in ways that seem straight out of science fiction. One striking example is superconductivity, where electrons glide through a material without any resistance—a phenomenon that could revolutionize everything from power grids to quantum computers.
In other cases, electrons arrange themselves into perfectly ordered patterns, almost like a synchronized dance troupe moving in perfect harmony. By studying these geometric properties, scientists could engineer new materials with cutting-edge electronic capabilities.
To observe this effect, the team turned to kagome metals, a class of materials named after their distinct lattice structure, which looks like a web of interlocking triangles. This pattern isn’t just visually striking—it directly influences how electrons move and transfer energy, potentially unlocking new frontiers in material science.
How ARPES Unlocks These Secrets
During ARPES experiments, researchers fire a beam of photons at a crystal, which knocks electrons loose from the material. By analyzing the angles and spins of these freed electrons, scientists can map out their geometric properties with incredible precision.
This isn’t just some deep dive into abstract physics—understanding electrons at this level could lead to major advancements in technology. Take quantum computing, for example. These futuristic machines rely on keeping electron states stable to process complex calculations. If scientists can decode how electron geometry works, they might be able to build more reliable quantum computers—and finally make them practical for everyday use.
Researchers aren’t stopping there. They’re fine-tuning techniques like ARPES to explore an even broader range of materials. The big question? How does quantum geometry affect things like electricity, magnetism, and other material properties that could shape the future of electronics and energy. While the discovery seems abstract to the average Joe, the application of this new piece of knowledge could jumpstart a New Age of technology, much like the Industrial Revolution.
Physicists are hoping to tame –or at least learn to predict– electrons movement patterns. If they study and gently guide their geometry, scientists might be able to guide these rebelious particles to form more synchronised patterns. If this herding of electrons proves successful, the discovery could be used in everything: from creating more efficient but circuits, to manufacturing cutting edge-quantum technology.

AstroSat is India’s first dedicated space astronomy observatory and the UVIT is one of the primary payloads which was developed by IIA.
Astronomers from the Indian Institute of Astrophysics (IIA) have spotted far ultra violet (FUV) emissions from novae for the first time in the neighbouring Andromeda galaxy.
The ultraviolet emissions from novae are a special class of transient astronomical event that causes the sudden appearance of a bright, apparently new star that slowly fades over weeks or months, during their outburst.
The IIA team used ultraviolet imaging telescope (UVIT/AstroSat) data of the Andromeda galaxy from public archives, to look for FUV emission from novae during their dormancy.
AstroSat is India’s first dedicated space astronomy observatory and the UVIT is one of the primary payloads which was developed by IIA.
According to the Department of Science and Technology, the team stumbled upon the novae around their eruption phase.
It added that the team, consisting of Judhajeet Basu (IIA and Pondicherry University), Krishnendu S. (IIA and Amrita University), Sudhanshu Barway (IIA), Shatakshi Chamoli (IIA and Pondicherry University), and G. C. Anupama (IIA), also discovered ultraviolet emission from 42 novae, a special class of stellar explosions, and even caught four of them in the act of outburst itself.
The department said that this could help scientists study these interacting binary star systems in our nearest neighbor galaxy at different phases of their life, some piling up matter from their companion, while others spewing it into space.
“UVIT’s fine spatial resolution and unique capability to observe simultaneously in far UV and near UV helped us investigate the fluxes in different UV bands, which led to the detection of accretion disks in some of these systems, 2.5 million light years away. The brighter the disk, the more rapidly it is consuming its companion’s matter. We also studied how the flux from these discs changes with time, and as per our expectations, the accretion process was found to be stable in these systems.” Mr. Basu, a PhD student at IIA, who led the project, said.
