Fully digital platform for local ultra-stable optical frequency distribution
Martina Matusko, Ivan Ryger, Gwenhaël Goavec-Merou +5
This article reports on the use of a Field Programmable Gate Array (FPGA) platform for local ultra-stable optical frequency distribution through a 90 m-long fiber network. This pla…
Heating rate measurement and characterization of a prototype surface-electrode trap for optical frequency metrology
Thomas Lauprêtre, Bachir Achi, Lucas Groult +4
We present the characterization of a prototype surface-electrode (SE) trap as a first step towards the realization of a compact, single-ion optical clock based on Yb. The use o…
Absolute frequency measurements of the transition in ytterbium
Thomas Lauprêtre, Lucas Groult, Bachir Achi +4
The ytterbium atom is widely used in the fields of atomic physics, cavity quantum electrodynamics, quantum information processing and optical frequency standards. There is however…
Single-ion, transportable optical atomic clocks
Marion Delehaye, Clément Lacroûte
For the past 15 years, tremendous progress within the fields of laser stabilization, optical frequency combs and atom cooling and trapping have allowed the realization of optical a…
Residual Phase Noise Measurement of Optical Second Harmonic Generation in PPLN Waveguides
Marion Delehaye, Jacques Millo, Pierre-Yves Bourgeois +6
We report on the characterization, including residual phase noise and fractional frequency instability, of fiber-coupled PPLN non-linear crystals. These components are devoted to f…
Connecting few-body inelastic decay to many-body correlations: a weakly coupled impurity in a resonant Fermi gas
Sébastien Laurent, Matthieu Pierce, Marion Delehaye +3
We study three-body recombination in an ultracold Bose-Fermi mixture. We first show theoretically that, for weak inter-species coupling, the loss rate is proportional to Tan's cont…
Critical Velocity and Dissipation of an ultracold Bose-Fermi Counterflow
Marion Delehaye, Sébastien Laurent, Igor Ferrier-Barbut +3
We study the dynamics of counterflowing bosonic and fermionic lithium atoms. First, by tuning the interaction strength we measure the critical velocity vc of the system in the BEC-…
Universal Loss Dynamics in a Unitary Bose Gas
Ulrich Eismann, Lev Khaykovich, Sébastien Laurent +8
The low temperature unitary Bose gas is a fundamental paradigm in few-body and many-body physics, attracting wide theoretical and experimental interest. Here we first present a the…
Chandrasekhar-Clogston limit and critical polarization in a Fermi-Bose superfluid mixture
Tomoki Ozawa, Alessio Recati, Marion Delehaye +2
We study mixtures of a population-imbalanced strongly-interacting Fermi gas and of a Bose-Einstein condensed gas at zero temperature. In the homogeneous case, we find that the Chan…
A Mixture of Bose and Fermi Superfluids
Igor Ferrier-Barbut, Marion Delehaye, Sebastien Laurent +5
Superconductivity and superfluidity of fermionic and bosonic systems are remarkable many-body quantum phenomena. In liquid helium and dilute gases, Bose and Fermi superfluidity has…
Λ-enhanced Sub-Doppler Cooling of Lithium Atoms in D1 Gray Molasses
Andrew T. Grier, Igor Ferrier-Barbut, Benno S. Rem +4
Following the bichromatic sub-Doppler cooling scheme on the D1 line of 40K recently demonstrated in (Fernandes et al. 2012), we introduce a similar technique for 7Li atoms and obta…
Density distribution of a trapped two-dimensional strongly interacting Fermi gas
Alexey A. Orel, Paul Dyke, Marion Delehaye +2
We calculate and measure the density distribution and cloud size of a trapped two-dimensional Li Fermi gas near a Feshbach resonance at low temperatures. Density distribution…
