Vortex profiles on (a) the BCS side with dimensionless interaction parameter G = 0.045 and (b) the BEC side with G = 0.053. The critical interaction parameter Gc = 0.049 is determined by Eq. (14) with other parameters being given as kFd = 0.2, t = 0.5eF, and k0 = 2 × 104kF. Solid and dotted lines represent the atom number density and the pair density, respectively.
