| contents | We demonstrate the formation of dynamically stable giant vortices in a harmonically-trapped strongly dipolar $^{164}$Dy Bose-Einstein condensate under rotation around the polarization direction of dipolar atoms, employing the numerical solution of an improved mean-field model including a Lee-Huang-Yang-type interaction, meant to stop a collapse at high atom density. These giant vortices are stationary, obtainable by imaginary-time propagation using a Gaussian initial state, while the appropriate phase of the giant vortex is imprinted on the initial wave function. The dynamical stability of the giant vortices is established by real-time propagation during a long interval of time after a small change of a parameter. |
