In 2014, Tobias Denkmayr and his colleagues split a stream of neutrons into two beams and conducted a series of measurements. It turned out that in certain circumstances, neutrons can be on one path, and their magnetic moment on another.
This proved the quantum paradox dubbed the “Cheshire Cat’s smile,” which is when particles and their properties can be perceived as being located in different areas of space, like the smile separated from the cat in Alice in Wonderland.
