"quantum anomalous Hall (QAH) effect... no energy loss as electrons flow along materials's edges and can make immediate U-turn... 5-millisecond current pulse to QAH insulator impacts internal magnetism and causes electrons change directions... electronic faster than magnetic switch... narrowing QAH insulator devices increased applied current's density... future: pause electrons en route and QAH effect at higher temperatures (currently near absolute zero)... information transfer, storage, and retrieval"
