Özet
Anisotropic transport of multiple vortices is investigated by a numerical simulation method in superconductors with triangular pinning arrays. The results are discussed by means of V(I) curves, structure factor, vortex flows, and velocity noise spectrum. The dynamical phase diagram as a function of the pinning strength is obtained to characterize the motion of the vortices. The results reveal the existence of a strong transport anisotropy when the multiple vortices (dimer state) are driven in two perpendicular directions. The anisotropic behavior is interpreted in terms of the triangular geometry of the pinning arrays and the nature of the competitive interactions of vortices with periodic arrays of the pinning centers.
