    "abstract": "Few-body systems with large scattering length have universal properties that\ndo not depend on the details of their interactions at short distances. We study\nthe universal bound state properties of the four-boson system with large\nscattering length in an effective quantum mechanics approach. We compute the\nfour-body binding energies using the Yakubovsky equations for positive and\nnegative scattering length. Moreover, we study the correlation between three-\nand four-body energies and present a generalized Efimov plot for the four-body\nsystem. These results are useful for understanding the cluster structure of\nnuclei and for the creation of weakly-bound tetramers with cold atoms close to\na Feshbach resonance.",
