Atomic and Molecular Physics

Viewpoint: Spins in cold atoms—what a drag!

Interactions among noncondensed bosonic atoms in a trap can cause one species of atoms accelerated by a magnetic field to drag along another species of atoms that would normally not interact with the field. Read More »

Semiconductor Physics

Viewpoint: Holes in the stream

Measurement of the Coulomb drag correlation in a two-dimensional electron gas provides a quantitative explanation for the movement of electron-hole packets opposite to the expected direction. Read More »
