Scientist, Deputy Division Head for APS-TD, Fermilab; Physics and Sensing Focus Area Leader, SQMS
Sam Posen leads the Physics and Sensing Focus Area, where they leverage the quantum technology and testbeds of SQMS to look for signs of beyond-the-standard-model physics. This includes searching for dark matter and developing novel detectors for gravitational waves.
Sam’s background is in superconducting radiofrequency cavities, a technology that enables Fermilab’s high sensitivity searches for extremely small signals. He is researching a number of innovative methods to perform these searches, including looking for excitation of an unpowered resonator, using multiple modes of a single resonator, looking for transmission of a signal from one resonator to another and performing high-precision measurements of trapped particles.
