(Phys.org) —So long, solitons: University of Chicago physicists have shown that a group of scientists were incorrect when they concluded that a mysterious effect found in superfluids indicated the ...

We numerically study the formation of vortex clusters in trapped Bose-Einstein condensates where vortices are initially imprinted in a line. We show that such a system exhibits a rich phenomenology ...

Tangles of string typically become knotted, from macroscopic twine down to long-chain macromolecules such as DNA. Here, we demonstrate that knotting also occurs in quantum wavefunctions, where the ...

The knots in your shoelaces are familiar, but can you imagine knots made from light, water, or from the structured fluids that make LCD screens shine? They exist, and in a new Nature Physics study, ...

A vortex is a physics phenomenon that occurs when a gas or a liquid moves in circles. At the center is a vortex line that the matter swirls around. They are formed when there is a difference in the ...

Researchers have shown that a group of scientists were incorrect when they concluded that a mysterious effect found in superfluids indicated the presence of solitons -- exotic, solitary waves. Instead ...
