                „Interfacing cold atoms and nanostructures"

Kivonatos ismertetés:
Trapping and manipulating atoms by means of microscopic traps has seen 
enormous advances within the last decade. Today, ultra-cold atom clouds, 
Bose-Einstein condensates, and Fermi gases are routinely trapped in 
conservative potential at the surface of microchips. Such cold atom/solid 
state hybrid systems pave the way towards the construction of novel quantum 
electronic circuits and quantum sensors.
In our experiments, we investigate the interface between atomic clouds and 
superconducting circuits. I report the trapping and coherent manipulation 
of atom clouds above a superconducting coplanar microwave cavity structure 
and discuss the possibility of coupling ground state and Rydberg excited 
atoms to the microwave field of the cavity.
Another subject of our research is the in-situ detection of single atomic 
spin transitions in a Bose-Einstein condensate. I report the realization of 
a state selective single atom detector and present data on counting atoms 
from a Bose-Einstein condensate in the presence of magnetic field noise.
