Phase space compression with an accelerated diode and mirror potential — •Sönke Schmidt¹, J. Gonzalo Muga², and Andreas Ruschhaupt¹ — ¹Institut für Theoretische Physik, LU Hannover, Germany — ²Departamento de Química Física, UPV-EHU, Bilbao, Spain

We propose a scheme to cool atoms by collision with an accelerated potential. To achieve phase space compression we combine this with an irreversible diodic device. An incoming beam of atoms can pass this diode only in one direction and thus becomes trapped between the diode and the potential. Furthermore it gets slowed due to subsequent collisions with both the moving potential and the diode. We show both analytical and numerical results and compare it to other schemes.
