报告摘要：

Quantum droplet describes a self-bound object that is stabilized by quantum effect. It has a long research history ever since the Kerson Huang's theoretical model in late 1950s and the intensive study of Helium nanodroplet in 1980s. In recent years, quantum droplet has regained great interest in ultracold gases thanks to its realization in both dipolar gases (since 2016) and in binary boson mixtures (2018). In this talk, I will discuss the unique properties of quantum droplet as compared to a repulsive Bose gas and a classical droplet. The former is reflected in its self-bound nature, which can be used to engineer curved geometry and stable vortex lattice in quantum Hall limit. The latter can be manifested in the quantum-fluctuation-driven slash dynamics and the quantum liquid-gas transition at zero T.  All these phenomena could be directly probed in realistic ultracold boson mixtures.
