Heavy fermions emerge at an atomic-layer interface, unlocking new ways to design quantum materials
Researchers at the University of Osaka have observed a heavy-fermion state at the interface of a one-atom-thick material and a copper crystal. This discovery provides new insights into quantum materials and could facilitate the development of unconventional superconductors.
Why it matters
Advancements in quantum material engineering are essential for the next generation of high-performance electronics and energy-efficient technologies.
