    "abstract": "We study the dynamics of quantum correlations in a class of exactly solvable\nIsing-type models. We analyze in particular the time evolution of initial Bell\nstates created in a fully polarized background and on the ground state. We find\nthat the pairwise entanglement propagates with a velocity proportional to the\nreduced interaction for all the four Bell states. Singlet-like states are\nfavored during the propagation, in the sense that triplet-like states change\ntheir character during the propagation under certain circumstances.\nCharacteristic for the anisotropic models is the instantaneous creation of\npairwise entanglement from a fully polarized state; furthermore, the\npropagation of pairwise entanglement is suppressed in favor of a creation of\ndifferent types of entanglement. The ``entanglement wave\u0027\u0027 evolving from a Bell\nstate on the ground state turns out to be very localized in space-time. Further\nsupport to a recently formulated conjecture on entanglement sharing is given.",
