Efimov states embedded in the continuum

ORAL

Abstract

By considering a multichannel generalization of the Fermi pseudopotential, we calculate the adiabatic hyperspherical potential curves for three interacting bosons. The resulting energy landscape has a rich and complex structure showing multiple length scales and internal symmetries. Our model indicates the existence of a universal diabatic potential curve which supports a series of quasistable Efimov states embedded in the three-body continuum. These states are energetically far removed from the scattering threshold, and can be accessed using spectroscopic methods, opening experimental possibilities for the exploration of a new realm of Efimov physics
