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…
