Query: Static and dynamic properties of bimerons in a frustrated ferromagnetic
  monolayer   Magnetic bimeron is a topological counterpart of skyrmions in in-plane
magnets, which can be used as a spintronic information carrier. We report the
static properties of bimerons with different topological structures in a
frustrated ferromagnetic monolayer, where the bimeron structure is
characterized by the vorticity $Q_{\text{v}}$ and helicity $\eta$. It is found
that the bimeron energy increases with $Q_{\text{v}}$, and the energy of an
isolated bimeron with $Q_{\text{v}}=\pm 1$ depends on $\eta$. We also report
the dynamics of frustrated bimerons driven by the spin-orbit torques, which
depend on the strength of the dampinglike and fieldlike torques. We find that
the isolated bimeron with $Q_{\text{v}}=\pm 1$ can be driven into linear or
elliptical motion when the spin polarization is perpendicular to the easy axis.
We numerically reveal the damping dependence of the bimeron Hall angle driven
by the dampinglike torque. Besides, the isolated bimeron with $Q_{\text{v}}=\pm
1$ can be driven into rotation by the dampinglike torque when the spin
polarization is parallel to the easy axis. The rotation frequency is
proportional to the driving current density. In addition, we numerically
demonstrate the possibility of creating a bimeron state with a higher or lower
topological charge by the current-driven collision and merging of bimeron
states with different $Q_{\text{v}}$. Our results could be useful for
understanding the bimeron physics in frustrated magnets.
