Phase-modulation detection of a strontium-atom-interferometer gyroscope

Physical Review Applied
We demonstrate a strontium thermal beam atom interferometer gyroscope (AIG) on a rotation table using the $^{1\!}S_0$-$ ^{3\!}P_1$ intercombination line, and measure large rotation rates exceeding 6 rad/s. Our demonstration relies upon a transit-time-resonant (TTR), phase modulation technique for detecting the AIG phase which rejects signal background ...

Narrow-line-mediated Sisyphus cooling in the ^{3}P_{2} metastable state of strontium

Physical Review Research
We demonstrate narrow-line-mediated Sisyphus cooling of magnetically trapped strontium (Sr) in the 5s5p^{3}P_{2} state. A 641nm standing-wave, blue detuned from the 5s4d^{3}D_{3}→ 5p4d^{3}F_{4} transition, creates a dissipative optical lattice in the ^{3}

Coherent Manipulation of Orbital Feshbach Molecules of Two-Electron Atoms

Physical Review X, 2019
Ultracold molecules have experienced increasing attention in recent years. Compared to ultracold atoms, they possess several unique properties that make them perfect candidates for the implementation of new quantum-technological applications in several ...

Atom interferometry with ultra-cold strontium

, 2015
We report on the the first realization of an atom interferometer based on alkali-earth atoms, namely strontium, using Bragg diffraction. The present status of the project and future prospects towards high precision tests in gravitational physics are discussed.

Deterministic nuclear spin squeezing and squeezing by continuous measurement using vector and tensor light shifts

SciPost Physics
We study the joint effects of vector and tensor light shifts in a set of large spin atoms, prepared in a polarized state and interacting with light. Depending on the ratio $\epsilon$ between tensor and vector coupling and a measurement rate $\Gamma$, we ...

An optical lattice clock with Strontium atoms

, 2008
Ce mémoire présente les dernières avancées de l'horloge à réseau optique à atomes de Strontium du LNE-SYRTE. Après avoir passé en revue les différents types d'horloges optiques actuellement développées, l'accent est mis sur le concept d'horloge à réseau optique qui a d'abord été formulé dans le cadre d'une horloge à 87Sr utilisant la transition 1S0 ...
