Scientists Discover Bizarre Material Where Electrons Stand Still

Rice University researchers have discovered a novel 3D crystalline metal that locks electrons in place due to a unique interplay of quantum correlations and the material’s geometric structure. This discovery highlights the role of flat electronic bands in determining a material’s properties and sets the stage for further explorations into quantum materials with pyrochlore lattice structures.
