Electrons successfully trapped in groundbreaking 3D crystal experiment

Physicists at MIT have successfully trapped electrons in a pure crystal, achieving an electronic flat band in a three-dimensional material for the first time. The crystal's unique atomic geometry, resembling the Japanese art of "kagome," allows the electrons to be trapped and settle into the same energy band. This breakthrough opens up new possibilities for studying rare electronic states in 3D materials and could lead to advancements in superconductivity and quantum technologies.
