Borromean states in a one-dimensional three-body system
Tobias Schnurrenberger, Lucas Happ, Maxim A. Efremov
We show the existence of Borromean bound states in a one-dimensional quantum three-body system composed of two identical bosons and a distinguishable particle. It is assumed that t…
Structure of Heavy Mesons in the Light-Front Quark Model
Ahmad Jafar Arifi, Lucas Happ, Shuhei Ohno +1
We investigate the structure of ground-state heavy mesons within the light-front quark model, utilizing wave functions derived from the Single Gaussian Ansatz (SGA) and the Gaussia…
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…
Universality in a one-dimensional three-body system
Lucas Happ, Matthias Zimmermann, Santiago I. Betelu +2
We study a heavy-heavy-light three-body system confined to one space dimension. Both binding energies and corresponding wave functions are obtained for (i) the zero-range, and (ii)…
