(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 ...

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 ...

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 ...
