An experiment has observed quantized charge accumulation in a system exhibiting the quantum anomalous Hall effect, its authors report. The finding provides direct experimental evidence of how charge organizes into discrete units in this class of topological materials, a phenomenon predicted in theory but difficult to isolate cleanly in the laboratory.
