Spin segregation via dynamically induced long-range interactions in a system of ultracold fermions
Spin segregation via dynamically induced long-range interactions in a system of ultracold fermions
We investigate theoretically the time evolution of a one-dimensional system of spin-1/2 fermions in a harmonic trap after, initially, a spiral spin configuration far from equilibrium is created. We predict a spin segregation building up in time already for weak interaction under realistic experimental conditions. The effect relies on the …
