Non-exponential tunneling due to mean-field induced swallowtails
Q. Guan, M. K. H. Ome, T. M. Bersano +3
Typically, energy levels change without bifurcating in response to a change of a control parameter. Bifurcations can lead to loops or swallowtails in the energy spectrum. The simpl…

Energetics and structural properties of two- and three-boson systems in the presence of 1D spin-orbit coupling
Qingze Guan, Doerte Blume
It was shown recently that the discrete scaling symmetry, which underlies the Efimov effect in the three identical boson system with two-body short-range interactions, survives whe…

Density Oscillations Induced by Individual Ultracold Two-Body Collisions
Q. Guan, V. Klinkhamer, R. Klemt +5
Access to single-particle momenta provides new means of studying the dynamics of a few interacting particles. In a joint theoretical and experimental effort, we observe and analyze…
