Quantum metric nonlinear spin-orbit torque enhanced by topological bands
Effects manifesting quantum geometry have been a focus of physics research. Here, we reveal that quantum metric plays a crucial role in nonlinear electric spin response, leading to a quantum metric spin–orbit torque. We argue that enhanced quantum metric can occur at band (anti)crossings, so the non...
