Molecular "vapor cell'' in a beaker

ORAL

Abstract

The fundamental sensitivity limit of a vapor cell magnetometer is constrained by the number of spins participating in the measurement, but there is a cap to the number density that gas phase systems can reach before spin-exchange collisions and radiation trapping become a problem. As an extrapolation of high density buffer gas, liquid systems can potentially take advantage of the extremely high number density (2t×1019/cc) of spins achievable in solution. Here we present a Yb3+ based molecular complex ((thiolfan)YbCl) that has an isolated, narrow, optical transition even when dissolved in solution at room temperature. We characterize the magnetic sensitivity of the transition via Zeeman splitting, demonstrating the potential application of (thiolfan)YbCl for magnetic sensing. We also report our current progress on spectral hole burning and optical state preparation and readout of ground state coherence in this liquid molecular system.
