When you shine a flashlight into a glass of water, the beam bends. That simple observation, familiar since ancient times, hides one of the oldest puzzles in physics: what really happens to the ...

A soccer player can kick a static ball on its side, forcing the ball to rotate and travel in an arc trajectory, left or right curved, depending on the ball's rotation sense. This requires ...

Topological spin textures, spatially organized patterns linked to the intrinsic angular momentum of particles, have proved to be highly advantageous for the development of spintronics and quantum ...
