"Magnetometers for Fetal Biomagnetism and Fundamental Physics"


Dr. Thad Walker
University of Wisconsin - Madison




Atomic magnetometry is now capable of sensitivities sufficient for detection of magnetic fields produced by human hearts and brains, and promises order-of-magnitude cost savings as compared to superconducting detectors.  In this talk I will describe how atomic magnetometers work, and present the first measurements of fetal magnetocardiography using a four detector array.  Then I will present new concepts for using these magnetometers for detection of nuclear magnetic resonance, and present results of a proof-of-principle experiment demonstrating two orders of magnitude improvement in the limits on P- and T- violating scalar-pseudoscalar couplings at 1 mm length scales.
