Designing optics for quantum matter-waves
|Date:||20 June 2019|
|Start:||16:00 (Doors open and coffee available at 15:30)|
Atoms are the ultimate quantum sensors for electro-magnetic fields and gravi¬tational forces. By a feat of nature, atoms occur with bosonic or fermionic attributes, but where produced otherwise identically without any “manufacturing tolerance”.
The QUANTUS collaboration , has developed a highly sophisticated, but yet compact and rugged matter-wave device that can be used, for example, as a portable inertial acceleration sensor as shown in Fig. 1. The ultimate stress test of this device was completed successfully on Jan. 21. 2017, when the MAIUS  sounding rocket mission carried the atomic chip experiment to 243 km above ground and back, performing matter-wave-interferometry at Mach 4.2. After returning from space, it was recovered and is fully operational.
In this presentation, I will discuss applications of matter-wave optics that can be done on such a device.
