Type II superconductors can be penetrated by magnetic field because they form triangular lattices of these structures.
A phenomenon of this type can occur in optical tweezers using Laguerre-Gaussian modes. Phenomena of this type can be linked by Josephson strings in stacks that resemble pancakes. The movement due to these entities in superfluid helium is quantized as Planck's constant over the mass of helium. These phenomena unpair from their opposite counterparts in the Kosterlitz-Thouless transition. Columnar defects can be used to trap these phenomena, which experience a (*) pinning force. Type II superconductors can be penetrated by magnetic field because they form triangular lattices of these structures. Shear causes these topological defects to experience "stretch" and "tilt". These phenomena are described by Helmholtz's three theorems, and are shed around an obstacle in a Von Karman street. These entities name a quantity equal to the curl of the flow velocity. For 10 points name these entities, regions of circular flow around a line.
