Physical Review A

In the quantum world particles can instantaneously know about each other’s state, even when separated by large distances. This is known as nonlocality. Now, A research group has produced some interesting findings on the Hardy nonlocality that have important ramifications for understanding quantum mechanics and its potential applications in communications.

Through numerical simulations, a researcher details the discovery of a new isolated skyrmion with a half-integer topological quantum number in the ferromagnetic phase of the magnetic quantum fluid Bose-Einstein condensate (BEC). The new skyrmion is generated by applying a spin current to a magnetic domain wall and it has an eccentric (off-center) spin singularity inside it.
