Coherent vortical structures appear in planetary atmospheres, oceans, laboratory experiments with rotating fluids, magnetized plasmas, pure electron plasma confined by a magnetic field, and dusty plasmas. Understanding the dynamics of coherent vortical structures in two-dimensional flows is of fundamental and practical interest in fluid dynamics, plasma physics, and Bose-Einstein condensate. The applications extend from transporting a trapped mass, heat, and momentum in large-scale weather patterns to plasma holes, electron columns confined in a Malmberg–Penning trap, dust particles under the action of plasma forces or charge gradients and vortex lattices in “rotating liquid helium bucket” passing through shallow layer water spinning in a bucket.
A joint Special Topic on coherent vortical structures in Physics of Fluids and Physics of Plasmas aims to bring the latest advancement in fluid dynamics, plasma physics, and Bose-Einstein condensate communities working on the canonical problem of coherent vortical structures. Papers related to vortices in plasmas should be submitted to Physics of Plasmas, while those related to vortices in other states of matter should be submitted to Physics of Fluids.
Topics covered include, but are not limited to:
- The analogy between the plasma, the fluid, and Bose-Einstein condensate
- “Point vortices” and satellite vortices
- Geophysical flows
- Transport and driving mechanisms in two-dimensional turbulence in fluids and (dusty) plasmas
- Electron columns and drift-waves in magnetized plasma
- Quantized vortices in Bose-Einstein condensate
