Discrete quantum droplets in one-dimensional optical lattices

We consider the dynamical model of quantum droplets (QDs) launched in a deep optical lattice. This setting is modeled by a one-dimensional discrete Gross-Pitaevskii equation with Lee-Huang-Yang corrections. We find that the hopping rate, C, plays a dominant role in characterizing the properties of the system. The system can be divided into two regions: the quasicontinuum (QC) and tightly-bound (TB) regions. In the QC region, where the hopping...
