Spin-entanglement of an atomic pair through coupling to their thermal motion
Poramaporn Ruksasakchai, Lucile Sanchez, Marvin Weyland +3
The spin-dynamics of two alkali atoms in an optical tweezer is driven by spin-changing collisions that couple the spin-state of the atoms to their relative motion. This paper exper…

Counterdiabatic driving for random-gap Landau-Zener transitions
Georgios Theologou, Mikkel F. Andersen, Sandro Wimberger
The Landau--Zener (LZ) model describes a two-level quantum system that undergoes an avoided crossing. In the adiabatic limit, the transition probability vanishes. An auxiliary cont…
