We study the existence and variational characterization of domain walls in a coupled system of Gross–Pitaevskii equations modeling two-component Bose-Einstein condensates with the magnetic field trapping. Domain walls arise as minimizers in a subspace of the energy space with a certain symmetry. We study bifurcation of the domain walls and furthermore give numerical illustrations of our results.
