Electrons successfully trapped in groundbreaking 3D crystal experiment

Physicists at MIT have successfully trapped electrons in a three-dimensional crystal for the first time, creating an electronic "flat band" state. This state allows electrons to behave collectively and exhibit quantum effects, potentially leading to superconductivity and unique forms of magnetism. The crystal's atomic geometry, resembling the Japanese art of basket-weaving called "kagome," allows the electrons to be trapped and settle into the same energy band. The researchers also demonstrated that by manipulating the crystal's composition, they could transform it into a superconductor. This breakthrough opens up new possibilities for exploring rare electronic states in three-dimensional materials and developing technologies such as ultraefficient power lines and faster electronic devices.
