Proof of universality in one-dimensional few-body systems including anisotropic interactions
Lucas Happ, Maxim A. Efremov
We provide an analytical proof of universality for bound states in one-dimensional systems of two and three particles, valid for short-range interactions with negative or vanishing…

Universality of excited three-body bound states in one dimension
Lucas Happ, Matthias Zimmermann, Maxim A. Efremov
We study a heavy-heavy-light three-body system confined to one space dimension provided the binding energy of an excited state in the heavy-light subsystems approaches zero. The as…
