In a recent study exploring the fundamentals of quantum physics, researchers examined how matter behaves at extremely small scales, including atoms, electrons, and photons. The work, led by Cal Poly Physics Department Lecturer Ian Powell, focused on how varying a magnetic field over time can cause matter to exhibit unusual and previously unseen properties.
Powell and student researcher Louis Buchalter, who earned a Cal Poly bachelor’s degree in physics in 2025, published their findings in Physical Review B in a paper titled “Flux-Switching Floquet Engineering.” Their research shows that when magnetic fields are changed in a controlled, time-dependent way, they can generate quantum states that do not exist in materials that remain unchanged over time (remaining in the same state as time elapses).
“On a big-picture level, I would describe this as an advance in our understanding of how time-dependent control can create and organize new forms of quantum matter,” Powell said. “The central idea is that useful quantum properties can depend not just on what a material is, but on how it is driven in time. In our case, we show that periodically changing a magnetic field can produce driven quantum phases with no static counterpart.”
Toward More Stable Quantum Technologies
By carefully timing how magnetic fields are applied, scientists can design quantum systems with properties that are more stable and less vulnerable to “noise” or imperfections. These disruptions are a major challenge in quantum technology, often leading to errors in calculations or system performance.
Powell noted that while the technical details can be difficult to explain outside the field, the broader concept is clear. The findings suggest new ways to create and study these unusual quantum states in controlled settings such as ultracold-atom experiments.

안녕하세요, 청소년 여러분! 최근 과학자들이 상상조차 하기 어려웠던 새로운 형태의 물질을 만들어냈다는 놀라운 소식이 전해졌습니다. 캘리포니아 폴리테크닉 주립대학교 (Cal Poly) 의 연구팀이 자기장을 시간에 따라 변화시키는 실험을 통해, 기존에는 존재할 수 없다고 생각했던 양자 상태의 물질을 발견한 것입니다. 마치 음악을 연주할 때 리듬을 바꿔주면 전혀 새로운 소리가 나듯이, 자기장의 변화를 조절하면 물질의 성질도 변할 수 있다는 것이죠. 이 연구는 양자 기술에서 중요한 문제인 ‘노이즈’나 오류를 줄이는 데 큰 도움이 될 것으로 기대됩니다. 미래의 컴퓨터나 기술 발전에 매우 유익한 발견이니 꼭 기억해 두세요!
