Researchers at Tohoku University and the Japan Atomic Energy Agency (JAEA) have successfully controlled a unique quantum phenomenon—the quantum-geometric nonlinear Hall (QgNLH) state—using electric current for the first time. The breakthrough was achieved by revealing and exploiting the coupling...
