Abstract
Quantum droplets have been recently observed in dipolar Bose–Einstein condensates (BECs) and in BEC mixtures. This forms the motivation for us to explore the dynamics of these droplets. We make use of the extended Gross–Pitaevskii equation which apart from the effective mean-field (MF) interaction also includes a beyond mean-field interaction. The competition of these two interactions in the context of droplet formation is explored. Further, the conditions for droplet formation are studied.
