The nonlinear dirac equation in Bose–Einstein condensates: vortex solutions and spectra in a weak harmonic trap
We analyze the vortex solution space of the $(2+1)$ -dimensional nonlinear Dirac equation for bosons in a honeycomb optical lattice at length scales much larger than the lattice spacing. Dirac point relativistic covariance combined with s-wave scattering for bosons leads to a large number of vortex...
