Self-sustained Josephson dynamics and self-trapping in supersolids
The study investigates self-sustained Josephson dynamics and self-trapping in dipolar supersolids using a triangular configuration of Bose gas atoms. By employing an Asymmetric Two-Mode (ATM) model, researchers demonstrated that the system exhibits clear Josephson oscillations near equilibrium but also displays self-trapping behavior when the initial population imbalance is large. This confirms that the Josephson junction is a key driver of the complex dynamics in these supersolids.
