Abstract:
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 [1], 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 [2] 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.
