Quantum mechanics governs the behavior of matter and energy at microscopic scales, yet many of its predictions remain counterintuitive and challenging to test. One of the most effective tools scientists use to explore these quantum phenomena is ultra-cold atoms—atoms cooled to temperatures near absolute zero. At such low temperatures, atoms behave in ways that reveal the fundamental rules of quantum physics, allowing researchers to test and verify theoretical predictions with unprecedented precision.

The universe as we see it today—a vast expanse of galaxies, stars, planets, and cosmic voids—did not always look this way. Its large-scale structure, from sprawling galaxy clusters to intricate filaments of dark matter, has roots in the tiny quantum fluctuations that occurred in the universe’s earliest moments. Understanding these fluctuations gives us insight into how order emerged from the primordial chaos.
