"Breakthrough: Scientists Uncover 2D Quantum Material with 100x More Mass"

Scientists from Uppsala and Columbia University have discovered a new 2D quantum material, CeSiI, with heavy fermions, marking the first instance of heavy fermions in a 2D structure. This breakthrough paves the way for advanced studies on quantum phenomena and the development of materials with tailored quantum properties. The material's unique 2D-like crystal structure with clearly separated, atom-thin layers opens up new possibilities for investigating correlated electron structures and creating materials with customized quantum properties.
