Generation of supersolids through barrier sweeps in a droplet lattice

We explore the dynamical formation of supersolid states in dipolar quantum gases by considering sweeps of a repulsive Gaussian barrier through quasi‑one‑dimensional droplet lattices. Relying on the suitable extended Gross-Pitaevskii framework incorporating quantum corrections, we discuss the impact of the sweep velocity on the build-up of phase coherence across the lattice due to collisions of the involved droplets. Monitoring the ensuing density dynamics, momentum distribution, and superfluid fraction reveals the generation of supersolidity. This is associated with the rise of a finite superfluid background atop which crystals oscillate and a momentum transfer toward zero modes. These results pave the way for engineering supersolid formation using experimentally accessible protocols.
