Abstract
dc.description.abstract
The equivalence between different physical systems permits us to transfer knowledge between them and to
characterize the universal nature of their dynamics. We demonstrate that a nanopillar driven by a spin-transfer
torque is equivalent to a rotating magnetic plate, which permits us to consider the nanopillar as a macroscopic
system under a time-modulated injection of energy, that is, a simple parametric resonator. This equivalence
allows us to characterize the phases diagram and to predict magnetic states and dynamical behaviors, such as
solitons, stationary textures, and oscillatory localized states, among others. Numerical simulations confirm these
predictions.
