A new type of quantum droplet - the most dilute liquids ever experimentally observed - helps unravel the mechanism leading to the formation of one dimensional self-bound quantum liquids in free space. Researchers present a microscopic theory of lattice quantum droplets.

Liquids are ubiquitous in Nature: from the water that we consume daily to superfluid helium which is a quantum liquid appearing at temperatures as low as only a few degrees above the absolute zero. A common feature of these vastly different liquids is being self-bound in free space in the form of droplets. Understanding from a microscopic perspective how a liquid is formed by adding particles one by one is a significant challenge.

Abstract:
Liquids are ubiquitous in Nature: from the water that we consume daily to superfluid helium which is a quantum liquid appearing at temperatures as low as only a few degrees above the absolute zero. A common feature of these vastly different liquids is being self-bound in free space in the form of droplets. Understanding from a microscopic perspective how a liquid is formed by adding particles one by one is a significant challenge.
Physicists propose a new theory to explain one dimensional quantum liquids formation
Researchers from the Institute of Cosmos Sciences of the University of Barcelona present a microscopic theory of lattice quantum droplets which explains the formation of a new type of quantum droplets that has been experimentally observed in ultracold atomic systems.
