antivortex
An antivortex is a topological defect characterized by a circulation or winding opposite to that of a reference vortex. In two-dimensional order-parameter fields, such as the phase of a superfluid or the orientation of spins in a magnet, a vortex surrounds its core with a certain sense of rotation, while an antivortex encircles with the opposite sense. Vortices and antivortices often appear as complementary defects and can annihilate each other to restore a uniform state.
In fluids and quantum fluids, antivortices are point-like or line-like defects where the local flow circulates
In two-dimensional systems with a complex order parameter, the dynamics of vortices and antivortices are central
In superconductors and superfluids, antivortices carry opposite circulation or magnetic flux compared with vortices. They can
In nanomagnetism and spintronics, antivortices describe spin textures with opposite curling of in-plane magnetization compared with
Overall, antivortices provide a counterpoint to vortices across fluids, quantum fluids, superconductors, and magnetic systems, reflecting
