Abstract

A unique feature of superfluidity is the frictionless flow below a critical velocity. This was first pointed out by L. D. Landau who argued that only above the speed of sound the excitations of linear or sound waves is energetically favoured (1) leading to a finite drag and to a break down of superfluidity. The superfluid motion of a dilute
