Quantized vortices can be generated in classical experiments of liquid helium and ultracold dilute gases to conduct fundamental and comparative studies of different superfluids. In a new report published in Science Advances, ...
Water whirlpools, smoke rings, violent tornados and spiral galaxies are all examples of twists in fluids, although very different each other. Analogous twists, but in the realm of light, have been created by the research ...
