✦ Synopsis

We study the trajectory of Efimov states for a trapped three-boson system when the two-body scattering length a is changed. We show that these states follow the route "virtual-bound-continuum resonance" state when a is varied, respectively, from large positive to negative values. For a < 0, we include the triatomic continuum resonance effect to extend the three-body recombination length for trap temperatures greater than zero. For a > 0, we predict trimer binding energies based on the recombination length and the two-body scattering length.
