Half-quantum vortices
Unlike to superfluid ⁴He the superfluid ³He-A support the existence of vortices with half-quantum of circulation as well as single quantum vortices. The singular single quanta vortices as well as nonsingular vortices with 2 quanta of circulation have been revealed in rotating ³He-A. However, the hal...
