Abstract :

Recently, the investigation of self-bound droplet states in Bose mixtures and dipolar ultracold gases has become a burgeoning area of interest. This novel state of matter is stabilized by quantum fluctuations and requires a minimum number of particles. Such an exquisite stabilization mechanism originates from the competition between the attractive mean-field energy and repulsive beyond mean-field effects furnished by the Lee-Huang-Yang corrections, arresting the mean-field collapse, forming ultradilute quantum droplet. This latter has opened a new avenue to explore a broad range of exciting physical phenomena such as supersolid states and polarons. Quantum droplets are also potentially promising for future technologies, including gravitational wave detectors and quantum sensors. This session will explore the current status of quantum droplets and their link with quantum fluctuations and will provide attendees an opportunity to share their perspectives on future directions. Ground-state properties of such a new state of matter and some of the major breakthroughs are also discussed.
