Non-Abelian Gauge Field Mechanics
Ivan Velkovsky, Carlos Camacho, Tomoki Ozawa +2
Non-Abelian gauge fields play a key role in describing the behavior of particles whose motion is coupled to internal degrees of freedom, such as their spin. Here, we experimentally…
Interaction-enabled topological pumping of Rydberg electrons
