Query: Motion-induced inertial effects and topological phase transitions in
  skyrmion transport   In this work, the current-induced inertial effects on skyrmions hosted in
ferromagnetic systems are studied. {When the dynamics is considered beyond the
particle-like description, magnetic skyrmions can deform due to a self-induced
field. We perform Monte Carlo simulations to characterize the deformation of
the skyrmion during its movement}. In the low-velocity regime, the deformation
in the skyrmion shape is quantified by an effective inertial mass, which is
related to the dissipative force. When skyrmions move faster, the large
self-induced deformation triggers topological transitions. The transition is
characterized by the proliferation of skyrmions and different total topological
charge, which are obtained in terms of the skyrmion velocity. Our findings
provide an alternative way to describe the skyrmion dynamics that take into
account the deformations of its structure. Furthermore, the motion-induced
topological phase transition brings the possibility to control the number of
ferromagnetic skyrmions by velocity effects.
