Swirling the weakly bound helium dimer from inside
Maksim Kunitski, Qingze Guan, Holger Maschkiwitz +9
Controlling the interactions between atoms with external fields opened up new branches in physics ranging from strongly correlated atomic systems to ideal Bose and Fermi gases and…
Mean-field spin-oscillation dynamics beyond the single-mode approximation for a harmonically trapped spin-1 Bose-Einstein condensate
Jianwen Jie, Q. Guan, S. Zhong +2
Compared to single-component Bose-Einstein condensates, spinor Bose-Einstein condensates display much richer dynamics. In addition to density oscillations, spinor Bose-Einstein con…
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…
Rabi oscillations and Ramsey-type pulses in ultracold bosons: Role of interactions
Q. Guan, T. M. Bersano, S. Mossman +2
Double-well systems loaded with one, two, or many quantum particles give rise to intriguing dynamics, ranging from Josephson oscillation to self-trapping. This work presents theore…
Nondestructive dispersive imaging of rotationally excited ultracold molecules
Qingze Guan, Michael Highman, Eric J. Meier +5
A barrier to realizing the potential of molecules for quantum information science applications is a lack of high-fidelity, single-molecule imaging techniques. Here, we present and…
