Physicists led by Lei Wang at Nanjing University discovered a new quantum state of matter called the transdimensional anomalous Hall effect in a thin carbon material, where electrons behave as if existing in neither two nor three dimensions when exposed to perpendicular magnetic fields. The unexpected phenomenon, which occurs in material between 2 and 5 nanometres thick, lacks the three-way symmetry found in conventional electronic states and represents a previously unknown regime distinct from established two- or three-dimensional cases.
