Abstract
Publisher Summary This chapter focuses on quantized vortices and the various configurations that occur. It discusses the structure of vortices, including the interaction with impurities, and deals with equilibrium vortex distributions, such as are induced by rotation. The chapter focuses on vortex lines, arrays of lines, and rings. It discusses steady state effects: friction on vortices, the interaction of heat flow and rotation in one particular geometry, vortex pinning, spin-up, and vortices in thin films. If helium II is contained in a rotating bucket, it is known experimentally that at low speeds of rotation, the normal fluid rotates with the container and the superfluid remain at rest. At a certain critical angular velocity of rotation, a single quantized vortex line appears in the center of the container. Experiments on helium II suggest that there are residual vortices present upon cooling through the lambda transition.
