We report recent advances in our studies on universality in four-bosonView original: http://arxiv.org/abs/1201.6586
systems. In particular, we are reporting results considering the solution of
Faddeev-Yakubovsky equations, within a renormalized zero-range interaction,
which are confirming a previous conjecture on four-body scale dependence. We
also discuss applications of the results in cold-atom systems.
