Towards detection of the molecular parity violation in chiral Ru(acac) and Os(acac)
Marit R. Fiechter, Pi A. B. Haase, Nidal Saleh +9
We present a theory-experiment investigation of the helically chiral compounds Ru(acac) and Os(acac) as candidates for the next-generation experiments for detection of mole…
Accurate determination of the Boltzmann constant by Doppler spectroscopy: Towards a new definition of the kelvin
Benoît Darquié, Sinda Mejri, Papa Lat Tabara Sow +6
Accurate molecular spectroscopy in the mid-infrared region allows precision measurements of fundamental constants. For instance, measuring the linewidth of an isolated Doppler-broa…
Quantum cascade laser frequency stabilisation at the sub-Hz level
Bérengère Argence, Bruno Chanteau, Olivier Lopez +7
Quantum Cascade Lasers (QCL) are increasingly being used to probe the mid-infrared "molecular fingerprint" region. This prompted efforts towards improving their spectral performanc…
Absorption line shape recovery beyond the detection bandwidth limit: application to the precision spectroscopic measurement of the Boltzmann constant
François Rohart, Sinda Mejri, Papa Lat Tabara Sow +8
A theoretical model of the influence of detection bandwidth properties on observed line shapes in laser absorption spectroscopy is described. The model predicts artificial frequenc…
A widely tunable 10-m quantum cascade laser phase-locked to a state-of-the-art mid-infrared reference for precision molecular spectroscopy
Papa Lat Tabara Sow, Sinda Mejri, Sean K. Tokunaga +7
We report the coherent phase-locking of a quantum cascade laser (QCL) at 10-m to the secondary frequency standard of this spectral region, a CO2 laser stabilized on a saturated…
The effect of self-affine fractal roughness of wires on atom chips
Z. Moktadir, B. Darquié, M. Kraft +1
Atom chips use current flowing in lithographically patterned wires to produce microscopic magnetic traps for atoms. The density distribution of a trapped cold atom cloud reveals di…
