Vortex configurations and vortex position.
(a) The scheme of composite vortices in Fig. 1(a). The size of the right molecular vortex which overlaps with an atomic vortex is bigger than the left one. (b) The scheme of carbon-dioxide-type vortex structure in Fig. 1(b). The size of the atomic vortex is bigger than that of the molecular vortex. The red, black and blue indicate the densities of atomic BEC, molecular BEC and the sum, respectively. (c), (d), (e) and (f) show the position of vortices in Figs. 1(a)–1(d), respectively. The circle (○) and asterisk (*) are the position of vortices formed by atomic BEC and molecular BEC, respectively. In (c), the red lines indicate that vortices can array in the square lattice. In (d), the blue lines show atomic vortices form the triangular lattice. While, the deviation of molecular vortices from the red lines indicates they form the amorphous state. In (e), atomic vortices form the triangular lattice and molecular vortices form the honeycomb lattices. Similarly, molecular vortices display the triangular lattice in (f). The unit of length is 1.07 μm.
