Researchers at Texas A&M University are developing highly sensitive quantum detectors to study dark matter. Led by Dr Rupak Mahapatra, the team has created sensors capable of detecting particles that rarely interact with ordinary matter. These detectors are helping scientists explore one of the Universe’s greatest mysteries.
“The challenge is that dark matter interacts so weakly that events may occur only once a year, or even once a decade,” Mahapatra said. His team is testing these detectors with the TESSERACT experiment, contributing to global dark matter searches.
The Mystery of Dark Matter and Dark Energy
Dark matter and dark energy together make up about 95 percent of the Universe, leaving only 5 percent as ordinary matter—the stuff we can see.
Neither dark matter nor dark energy emits, absorbs, or reflects light, which makes them nearly impossible to observe directly. Yet their gravitational effects shape galaxies and cosmic structures.
Dark energy dominates roughly 68 percent of the Universe’s total energy content, while dark matter accounts for about 27 percent. Understanding these components is essential to grasping the full picture of the cosmos.
Pushing the Limits of Detection
Mahapatra has spent 25 years advancing detection technologies, including work on the SuperCDMS experiment. In 2014, he helped introduce voltage-assisted calorimetric ionization detection, a breakthrough that allowed researchers to study low-mass WIMPs, a leading dark matter candidate.
This technique greatly increased sensitivity to particles that were previously undetectable. Mahapatra’s innovations continue to expand what scientists can measure in the lab.
A Global, Multi-Pronged Approach
Understanding dark matter requires multiple experimental strategies. In 2022, Mahapatra co-authored research on combining direct detection, indirect detection, and collider searches for WIMPs.
“No single experiment will give us all the answers,” he said. “We need synergy between different methods to piece together the full picture.”
Detecting dark matter is not just an academic goal. It could reveal fundamental laws of nature and inspire new technologies that are beyond our current imagination.
Toward a New Chapter in Physics
According to Mahapatra, successfully detecting dark matter could open a transformative chapter in physics. Quantum sensing technologies like those developed at Texas A&M are essential to reaching that goal.
