Interaction-induced period shift of the Kohn oscillation in a parity-time-symmetric harmonic trap
Gaoqing Meng, Mingshu Zhao
The center of mass of a Bose--Einstein condensate in a harmonic trap oscillates at the trap frequency independently of the interactions. Without interactions a parity-time-symmetri…

Solitonic Solutions of the One-Dimensional Harmonically Trapped Repulsive Bose-Einstein Condensate via Neural Network Quantum States
Gaoqing Meng, Mingshu Zhao
We demonstrate the existence of bright solitons in a repulsively interacting, harmonically trapped quasi-one-dimensional Bose-Einstein condensate described by the Gross-Pitaevskii…
