Borromean states in a one-dimensional three-body system — •Tobias Schnurrenberger1, Lucas Happ2, and Maxim Efremov1 — 1German Aerospace Center (DLR), Institute of Quantum Technologies, 89081 Ulm, Germany — 2RIKEN Nishina Center, Strangeness Nuclear Physics Laboratory, Wako 351-0198, Japan
We explore the Borromean states of a one-dimensional quantum three-body system composed of two identical heavy particles and a different particle of smaller mass. There is no heavy-heavy interaction potential and no bound state supported by the heavy-light one. To determine the parameters of the heavy-light potential for which the Borromean states may exist, we apply and compare two approaches: (i) the Born-Oppenheimer approximation, being usually valid for a large mass ratio between heavy and light particles, and (ii) the Faddeev equations, being exact for any mass ratio.
