Quantum Catcher - Stopping Particles of unknown velocities — •Sönke Schmidt¹, J. Gonzalo Muga², and Andreas Ruschhaupt¹ — ¹Institut für Mathematische Physik, TU Braunschweig, Mendelssohnstrasse 3, 38106 Braunschweig — ²Departamento de Quimica-Fisica, Universidad del Pais Vasco, Apartado 644, 48080 Bilbao, Spain

We propose a method to stop particles of unknown velocities. We present a classical and a quantum mechanical description of the setting. Using numerical simulations with realistic and experimentally accessible parameters, we show the efficiency of the method and discuss its bounds.
