Here we highlight this progress, with a particular focus on research efforts at NIST and JILA. We discuss advances in frequency instability and the characterization of key systematic effects, with a brief outlook to the future. © 2015 Published by Elsevier Masson SAS on behalf of Académie des sciences.

Precision measurement of fermionic collisions using an 87Sr optical lattice clock with 1 x 10(-16) inaccuracy.
We describe recent progress on the JILA Sr optical frequency standard, which has a systematic uncertainty at the 10(¿16) fractional frequency level. The dominant contributions to the systematic error are from blackbody radiation shifts and collisional shifts. We discuss the blackbody radiation shift and propose measurements and experimental protocols that should reduce its systematic contributi...
متن کاملEffects of Circadian Rhythm on Physical and physiological Performance of Military forces- Narrative Review
The 2017 Nobel Prize for medicine was awarded the biological clock Scientist, which shows the importance of this phenomenon in the life of living organisms. The circadian Rhythm (CR) through the created internal “clock” is responsible for regulating the daily performance of different organs of the body. The central body clock is the key factor to creating and maintaining this CR. External optic...
متن کاملInvestigating the Properties of an Optical Waveguide Based on Photonic Crystal with Point Defect and Lattice Constant Perturbation
In this paper, a photonic crystal waveguide with point defects and lattice constant perturbations of +5%, -5% are being investigated. Firstly waveguide structures with constant and specific parameters are being studied and photonic band gap diagrams for TE/TM modes are depicted; then pulse propagation in the frequencies available in the band gap are shown. After that, effects of parameters like...
متن کاملCoherence of Spin-Polarized Fermions Interacting with a Clock Laser in a Stark-Shift-Free Optical Lattice
We investigated the coherence of spin-polarized Sr atoms trapped in a light-shift-free one-dimensional optical lattice during their interaction with a clock laser on the S0 − P0 transition. Collapses and revivals appeared for more than 50 Rabi cycles, attributed to the thermal distribution of discrete vibrational states in the lattice potential. The population oscillation in the clock states la...
متن کاملEntangling the lattice clock: Towards Heisenberg-limited timekeeping
A scheme is presented for entangling the atoms of an optical lattice to reduce the quantum projection noise of a clock measurement. The divalent clock atoms are held in a lattice at a “magic” wavelength that does not perturb the clock frequency—to maintain clock accuracy—while an open-shell J = 1/2 “head” atom is coherently transported between lattice sites via the lattice polarization. This po...
