TOPIC: Progress in Two-Dimensional Quantum Turbulence

Abstract
The motion of 2D superfluid vortices supports a rich phenomenology including the chaotic states of quantum turbulence. I will give an outline of foundational concepts in theoretical understanding 2DQT, including vortex injection, energy spectra, and transport in Bose-Einstein condensates. I will also describe more recent developments including the reformulation of the point-vortex model in the hydrodynamic regime as a novel vortex fluid with anomalous stress tensor due to the quantized nature of the vortex cores. Current experimental efforts and future challenges for theory and experiment will also be described.
