Classical-linear-chain behavior from dipolar droplets to supersolids

We investigate the classicality of linear dipolar droplet arrays through a normal mode analysis of the dynamical properties in comparison to the supersolid regime. The vibrational patterns of isolated-droplet crystals that time-evolve after a small initial kick closely follow the properties of a linear droplet chain. For larger kick velocities, however, droplets may coalesce and separate again, showing distinct deviations from classicality. In the supersolid regime the normal modes are eliminated by a counterflow of mass between the droplets, signaled by a reduction of the center-of-mass motion. Our study effectively captures the vibrational patterns of isolated droplets in the presence of three-body loss and can be generalized to systems with a larger number of droplet arrays.

Automated summary

We investigate the classicality of linear dipolar droplet arrays through normal mode analysis and compare it with the supersolid regime. The vibrational patterns of isolated droplet crystals evolving over time after a small initial kick closely resemble those of a linear droplet chain. However, for larger kick velocities, droplets may coalesce and separate again, showing significant deviations from classicality. In the supersolid regime, the normal modes are eliminated by a counterflow of mass between the droplets, resulting in a reduction of the center-of-mass motion. Our study effectively captures the vibrational patterns of isolated droplets in the presence of three-body loss and can be extended to systems with a larger number of droplet arrays.
