Kivonat: 
“Bose-Einstein condensates of ultracold atoms can be used to sense 
fluctuations of the magnetic field by means of transitions into untrapped 
hyperfine states. It has been shown recently that counting the outcoupled 
atoms can yield the power spectrum of the magnetic noise. We calculate the 
spectral resolution function which characterizes the condensate as a noise 
measurement device in this scheme. We use the description of the 
radio-frequency outcoupling scheme of an atom laser which takes into account 
the gravitational acceleration. Employing both an intuitive and the exact 
three-dimensional and fully quantum mechanical approach we derive the 
position-dependent spectral resolution function for condensates of different 
size and shape.”

Minden érdeklődőt szeretettel várunk.
