Efimov states embedded in a quenched unitary Bose-condensed gas.

Abstract

Three identical bosons at unitarity may form a series of three-body bound states whose spectrum was first given by Efimov. Recently, a macroscopic population of Efimov molecules was measured for the first time in a Bose-condensed gas quenched to unitarity. Through the method of cumulants, we study three-body physics in the many-body context. We report preliminary results for the spectrum of two- and three-body bound states embedded in the quenched unitary Bose-condensed gas. This study is in preparation for studying the dependence of macroscopic observables on Efimov physics. Netherlands Organisation for Scientific Research (NWO) under Grant 680-47-623.
