摘　　要：We report the quantized superfluid vortex filaments induced by the axial flow effect,which exhibit intriguing loop structures on helical vortexes.Such new vortex filaments correspond to a series of soliton excitations including the multipeak soliton,W-shaped soliton,and anti-dark soliton,which have no analogue when the axial flow effect is absent.In particular,we show that the vortex filaments induced by the multipeak soliton and W-shaped soliton arise from the dual action of bending and twisting of the vortex,while the vortex filament induced by the anti-dark soliton is caused only by the bending action,which is consistent with the case of the standard bright soliton.These results will deepen our understanding of breather-induced vortex filaments and will be helpful for controllable ring-like excitations on vortices.
