Entanglement-enhanced optical magnetometry beyond the standard quantum limit

Jun Jia, Túlio Brito Brasil, Maimouna Bocoum +6

Optical atomic magnetometry is a powerful tool for continuous sensing applications, yet, in the absence of quantum correlations, its sensitivity is limited by the standard quantum…

High-Field Optical Cesium Magnetometer for Magnetic Resonance Imaging

Hans Stærkind, Kasper Jensen, Jörg H. Müller +3

We present a novel high-field optical quantum magnetometer based on saturated absorption spectroscopy on the extreme angular-momentum states of the cesium D2 line. With key feature…

Collectively enhanced Ramsey readout by cavity sub- to superradiant transition

Eliot Bohr, Sofus L. Kristensen, Christoph Hotter +6

When an inverted ensemble of atoms is tightly packed on the scale of its emission wavelength or when the atoms are collectively strongly coupled to a single cavity mode, their dipo…

Acoustic frequency atomic spin oscillator in the quantum regime

Jun Jia, Valeriy Novikov, Tulio Brito Brasil +3

We experimentally demonstrate quantum behavior of a macroscopic atomic spin oscillator in the acoustic frequency range. Quantum back-action of the spin measurement, ponderomotive s…

Sub-Natural Linewidth Superradiant Lasing with Cold Sr Atoms

Sofus Laguna Kristensen, Eliot Bohr, Julian Robinson-Tait +3

Superradiant lasers operate in the bad-cavity regime, where the phase coherence is stored in the spin state of an atomic medium rather than in the intracavity electric field. Such…

Precision Measurement of the Excited State Landé g-factor and Diamagnetic Shift of the Cesium D Line

Hans Stærkind, Kasper Jensen, Jörg H. Müller +3

We have performed saturated absorption spectroscopy on the cesium D line in 3 T and 7 T magnetic fields. By means of sideband spectroscopy on the extreme angular momentum sta…
