Mechanisms catalyzing dynamical generation of supersolidity

Determine the physical mechanisms that catalyze the dynamical generation of supersolidity in ultracold dipolar quantum gases, beyond the empirical observation that interaction quenches can produce supersolid states, in order to clarify how coherence and crystalline order are dynamically established under various drivings.

Background

Supersolids in dipolar quantum gases combine superfluidity with crystalline order and have been realized experimentally, often via interaction quenches. While realizations exist, the underlying dynamical pathways by which supersolidity emerges remain insufficiently characterized.

Recent studies indicate that heating, minority components in mixtures, or fermionic impurities can facilitate supersolidity, suggesting multiple possible routes. The present work proposes barrier sweeps through droplet arrays as another route, highlighting the broader unresolved issue of identifying and understanding the mechanisms that drive dynamical supersolid formation.
