Long range interactions between dark vectorial temporal cavity solitons are induced though the spontaneous symmetry breaking of orthogonally polarized fields in ring resonators. Turing patterns alternating polarizations form adjacent solitons, pushing them apart so that a random distribution along length reaches equal equilibrium distances. Enhancement frequency comb is achieved through formation regularly spaced soliton crystals, 'self-crystallization', with greater power and spacing spectral lines for increasing numbers.
