Liquid helium is a many-body system that exhibits remarkable
properties at sufficiently low temperatures. One such property is
superfluidity in which the fluid can flow without any dissipation.
Bose-Einstein condensation of a dilute atomic gas in 1995 marked the
appearance of another “quantum liquid” displaying similar remarkable
properties. In my talk, I will describe some aspects of superfluidity,
why they are still interesting and experiments to study these aspects
using quantum degenerate atomic Bose gases.
