First quantum simulation of 3D topological matter with ultracold atoms

Physicists from the Hong Kong University of Science and Technology (HKUST) and Peking University (PKU) have successfully created the world's first 3D simulation of topological matter consisting of ultracold atoms. Previous attempts at topological matter simulations were limited to lower dimensions, due to challenges on how to characterize 3D band topology in atomic systems. This breakthrough paves an opening to further examining new topological matter that cannot be well realized in solids. Such never-before-done engineering artificial material with ultracold atoms may allow physicist to model unusual phases of matter.
