Experimenting an optical second with strontium lattice clocks
R. Le Targat, L. Lorini, Y. Le Coq +17
Progress in realizing the SI second had multiple technological impacts and enabled to further constraint theoretical models in fundamental physics. Caesium microwave fountains, rea…
A neutral atom frequency reference in the deep UV with 10^(-15) range uncertainty
J. J. McFerran, L. Yi, S. Mejri +5
We present an assessment of the (6s^{2})1S0 -> (6s7s)3P0 clock transition frequency in 199Hg with an uncertainty reduction of nearly three orders of magnitude and demonstrate an at…
Ultra-low noise microwave generation with fiber-based optical frequency comb and application to atomic fountain clock
J. Millo, M. Abgrall, M. Lours +8
We demonstrate the use of a fiber-based femtosecond laser locked onto an ultra-stable optical cavity to generate a low-noise microwave reference signal. Comparison with both a liqu…
Pump-probe measurement of atomic parity violation in caesium with a precision of 2.6%
Michel Lintz, Jocelyne Guéna, Marie-Anne Bouchiat
We present the atomic parity violation measurements made in Cs vapour using a pump-probe scheme. After pulsed excitation of the 6S-7S forbidden transition in the presence of a long…
Proposal for high-precision Atomic Parity Violation measurements using amplification of the asymmetry by stimulated emission in a transverse E and B field pump-probe experiment
J. Guéna, M. Lintz, M. A Bouchiat
Amplification by stimulated emission of radiation provides an intriguing means for increasing the sensitivity of Atomic Parity Violation (APV) measurements in a pump-probe configur…
Cylindrical Symmetry Discrimination of Magnetoelectric Optical Systematic Effects in a Pump-probe Atomic Parity Violation Experiment
M-A. Bouchiat, J. Guéna, M. Lintz
A pump-probe atomic parity violation (APV) experiment performed in a longitudinal electric field, provides a signal breaking mirror symmetry while preserving the cylindrical symmet…
