“Intrinsic Gradient Magnetometry Using Atom Inter-ferometers.”

Atom interferometers have been demonstrated to be exquisitely sensitive to external forces that can act on the atoms in the interferometer. For this reason, atom interferometers are not only at the heart of many precision measurement laboratory apparatuses, but also at the heart of many sensors. These sensors include gravimeters, gravity gradiometers, gyroscopes and clocks. However, magnetometers are not found on this list. In this talk, I explore the possibility of using atom interferometers to measure magnetic fields. We will find that atom interferometers are actually insensitive to magnetic fields (to first order) but are sensitive to magnetic field gradients, making them an INHERENTLY gradient device. Such a device is currently under construction at Pax River and I will review its current status, as well as its potential impact to problems of interest to the Navy.
