Abstract

The topological force and torque are investigated in systems with spin-orbit coupling. It is demonstrated that the topological force and torque appears as a pure relativistic quantum effect in an electromagnetic field. The origin of both topological force and torque is the Zitterbewegung effect. Considering nonlinear behaviors of spin-orbit coupling, we address possible novel phenomena driven by the topological forces.
