Efimov states in Li-Cs mixtures within a minimal model
arXiv:1403.0759 · doi:10.1007/s00601-015-0959-y
Abstract
We use a minimal zero-range model for describing the bound state spectrum of three-body states consisting of two Cesium and one Lithium atom. Using a broad Feshbach resonance model for the two-body interactions, we show that recent experimental data can be described surprisingly well for particular values of the three-body parameter that governs the short-range behavior of the atomic potentials and is outside the scope of the zero-range model. Studying the spectrum as a function of the three-body parameter suggests that the lowest state seen in experiment could be influenced by finite range corrections. We also consider the question of Fermi degeneracy and corresponding Pauli blocking of the Lithium atoms on the Efimov states.
