Take quantum vortices, which are basically whirlpools of angular momentum in materials like superconductors and superfluids, giving them strange properties.
It's hoped such research will help create materials which could be used in new generations of electronics and superconductors, or in quantum computers.
When you have a type 2 superconductor in a powerful magnetic field. you get this thing called the Meissner effect, which means that you can actually lock on to it and hold it in place and manipulate it.
