Description
Nonequilibrium driving can generate strongly asymmetric responses even in systems without net bias or static symmetry breaking. We consider a framework for controlling vortices in a Bose–Einstein condensate confined to a ring trap through dynamical instabilities. When the system is periodically driven across an instability threshold, the resulting nonlinear response produces asymmetric growth and decay cycles that allow vortices to be deterministically switched on and off, even in symmetric settings. These dynamics provide a natural route to instability-enabled control in driven quantum fluids.
