Dmitry Budker develops optical methods for measuring weak magnetic fields. Resonant light interacts with an atomic vapor, preparing or probing atomic polarization whose evolution depends on the field. Measuring an optical signal therefore converts atomic magnetic response into a sensitive magnetometer. His coauthored review connects this method with geomagnetic sensing, detection of nuclear magnetic resonance and tests of fundamental symmetries.[ref]

Michael Romalis develops optical magnetometry, in which resonant light prepares or reads an atomic vapour's response to a magnetic field. His review with Dmitry Budker explains how atomic spin dynamics can provide sensitive magnetic sensing.[ref]

The atoms supply the field-sensitive reference, and changes of transmitted or emitted light provide the readout. The approach connects atomic physics with measurements of weak biological or geophysical magnetic fields, rather than requiring a conducting pickup coil for every measurement.
