atom 4d4d atomic orbitals. There are five 4d orbitals. These are labelled 4d xy, 4d xz, 4d yz, 4d x 2-y 2 and 4d z 2. The 4d z 2 name is an abbreviation for 3d (3z 2 –rWe demonstrate that AI can learn atomistic systems in the four-dimensional (4D) spacetime. For this, we introduce the 4D-spacetime GICnet
