insertion of angular momentum

David Peter, Axel Griesmaier, Tilman Pfau, Hans Peter Büchler
A new method to drive a system of neutral dipolar fermions to the lowest Landau level regime is proposed. By employing adiabatic spin-flip processes in combination with a diabatic transfer, the fermions are pumped to higher orbital angular momentum states in a repeated scheme that allows for the precise control over the final angular momentum. A simple analytical model is derived to quantify the transfer and compare the approach to rapidly rotating systems. Numerical simulations of the transfer process have been performed for small, interacting systems.
