Microscopic Approaches to Quantum Liquids in Confined Geometries.
Quantum liquids in confined geometries exhibit a large variety of new and interesting phenomena. For example, the internal structure of the liquid becomes more pronounced than in bulk liquids when the motion of the particles is restricted by an external matrix. Also, free quantum liquid droplets ena...
