Query: Quantum turbulence in atomic Bose-Einstein condensates   Weakly interacting, dilute atomic Bose-Einstein condensates (BECs) have
proved to be an attractive context for the study of nonlinear dynamics and
quantum effects at the macroscopic scale. Recently, atomic BECs have been used
to investigate quantum turbulence both experimentally and theoretically,
stimulated largely by the high degree of control which is available within
these quantum gases. In this article we motivate the use of atomic BECs for the
study of turbulence, discuss the characteristic regimes of turbulence which are
accessible, and briefly review some selected investigations of quantum
turbulence and recent results. We focus on three stages of turbulence - the
generation of turbulence, its steady state and its decay - and highlight some
fundamental questions regarding our understanding in each of these regimes.
