Supersolid behavior of a dipolar quantum gas

April 2019. The LENS team has found experimentally a regime in which a quantum gas of magnetic atoms has supersolid properties, i.e. it behaves simultaneously as a solid and a superfluid [1,2]. This discovery ends a quest lasting more than 15 years, motivated by the seminal theory work by outstanding theorists, among which the QUIC... Continue Reading →

Self-bound liquid droplets in free space

March 2018. The LENS team observed the formation of liquid-like droplets in a quantum gas of ultracold atoms in free space. These atomic systems result to be confined on a finite volume even in the absence of any external potential, due to a self-binding mechanism coming from the competition of attractive and repulsive forces in...

A new phase of matter: quantum liquid droplets

January and March 2018: In two recent papers published during the first trimester of 2018, the ICFO team has observed and studied for the first time a novel type of ultra-dilute quantum liquid that goes beyond the standard van der Waals paradigm. This liquid forms droplets: macroscopic clusters of ultra-cold atoms that are eight orders... Continue Reading →
