Coherent perfect absorption of nonlinear matter waves Open
Eliminating atoms of a Bose-Einstein condensate in a lattice from one cell is coherent perfect absorption of the quantum liquid.

A high repetition deterministic single ion source Open
We report on a deterministic single ion source with high repetition rate and high fidelity. The source employs a magneto-optical trap, where ultracold rubidium atoms are photoionized. The electrons herald the creation of a corresponding io…

Large numbers of cold positronium atoms created in laser-selected Rydberg states using resonant charge exchange Open
Lasers are used to control the production of highly excited positronium atoms (Ps*). The laser light excites Cs atoms to Rydberg states that have a large cross section for resonant charge-exchange collisions with cold trapped positrons. Fo…
