Triatomic continuum resonances for large negative scattering lengths

Abstract: We study triatomic systems in the regime of large negative scattering lengths which may be more favorable for the formation of condensed trimers in trapped ultracold monoatomic gases as the competition with the weakly bound dimers is absent. The manipulation of the scattering length can turn an excited weakly bound Efimov trimer into a continuum resonance. Its energy and width are described by universal scaling functions written in terms of the scattering length and the binding energy, $B_3$, of the shallowest… Show more

“…Moving opposite by decreasing the attraction, these states, one by one, cease to be bound. They move into the continuum and continue as resonances [26]. For asymmetric systems with a bound two-body subsystem, the three-body bound state passes through the particle-dimer threshold, becoming a virtual state [27].…”

“…Nesta seção iremos também calcular as energias das ressonâncias no sistema de três corpos. Mostraremos que partindo-se de uma certa energia para o estado ligado de dois corpos e diminuindo o seu módulo, um estado virtual de três corpos torna-se ligado [7], esse estado ligado torna-se por sua vez uma ressonância quando a energia de dois corpos torna-se virtual [49].…”
