Stopping particles of arbitrary velocities with an accelerated wall — •Sönke Schmidt¹, J. Gonzalo Muga², and Andreas Ruschhaupt¹ — ¹Institut für Theoretische Physik, Leibniz Universität Hannover, Germany — ²Departamento de Quimica Fisica, UPV-EHU, Bilbao, Spain

We propose a method to stop a pulse of particles with different velocities by making them collide with an accelerated wall with trajectory proportional to the square root of time. We discuss the ideal one-dimensional case. Then we generalize the model to three dimensions and different geometries of the potential wall to give a more realistic description. Finally we show the efficiency of the method.
