LEPP Joint Seminar: Itay Bloch (Tel Aviv)

Physical Sciences Building, 401
245 East Avenue

Comagnetometers as a Probe to New Physics
Abstract: The noble-alkali comagnetometer, developed in recent years, has been shown to be a very accurate measuring device of anomalous magnetic-like fields. An ultra-light relic axion-like particle can source such an anomalous field, allowing for its detection by such comagnetometers. In this talk I will explain how comagnetometers work, and show the new constraints on relic axion-like particles from old comagnetometer data. These constraints are the best of any terrestrial probe over a range of masses. Future experiments which we are currently building could reach unrivaled sensitivity in the ultra-low mass regime.
