College Pk: Amer Physical Soc, v. 107, n. 13, p. 5, 2011.0031-9007http://hdl.handle.net/11449/24614We evidence the existence of a universal correlation between the binding energies of successive four-boson bound states (tetramers), for large two-body scattering lengths (a), related to an additional scale not constrained by three-body Efimov physics. Relevant to ultracold atom experiments, the atom-trimer relaxation peaks for vertical bar a vertical bar -> infinity when the ratio between the tetramer and trimer energies is similar or equal to 4.6 and a new tetramer is formed. The new scale is also revealed for a < 0 by the prediction of a correlation between the positions of two successive peaks in the four-atom recombination process.5engArtigo10.1103/PhysRevLett.107.135304WOS:000299823200001Acesso abertoWOS000299823200001.pdf37406397265453158621258845956348
