Universal Properties of Near-Threshold Single-Neutron Resonances
Myungkuk Kim, Young-Ho Song, Hans-Werner Hammer +3
We establish universal width predictions for near-threshold single-neutron resonances in partial waves. Our results go beyond Wigner's well-known scaling behavior of cross…

Effective theory for strongly attractive one-dimensional fermions
Timothy G. Backert, Fabian Brauneis, Matija Čufar +3
We study a one-dimensional system of two-component fermions in the limit of strong attractive particle-particle interactions. First, we analyze scattering in the corresponding few-…

Two-dimensional bosonic droplets in a harmonic trap
Fabian Brauneis, Artem G. Volosniev, Hans-Werner Hammer
We investigate a system of bosons in a two-dimensional harmonic trap. In the limit of strong attractive interactions, the bosons make a droplet insensitive to external confinement.…
