- Authors: A. Sharma, S. Kolkowitz, and M. Saffman
- Abstract summary: We propose and analyze a Cesium lattice optical clock (CLOC) which has the potential for high performance and simple operation in a compact form factor.
Cs atoms are trapped in a 3D optical lattice using a magic trap wavelength of $lambda_textrm m=803textrm nm$.
Operation of the clock requires only three diode lasers at 685, 803, 852 nm and is simplified compared to other higher-performance optical clocks that rely on alkaline earth atoms or single trapped ions.

- Abstract: We propose and analyze a Cesium lattice optical clock (CLOC) which has the
potential for high performance and simple operation in a compact form factor
using a forbidden optical transition in Cs atoms at 685 nm. Cs atoms are
trapped in a 3D optical lattice using a magic trap wavelength of
$\lambda_{\textrm m}=803~\textrm nm$. To reduce sensitivity to magnetic fields
the atoms are probed on two cycling transitions with equal magnitude, but
opposite magnetic shifts. Operation of the clock requires only three diode
lasers at 685, 803, 852 nm and is simplified compared to other
higher-performance optical clocks that rely on alkaline earth atoms or single
trapped ions. Analysis shows a quantum noise limited stability of $8.4\times
10^{-16}/\sqrt\tau$ and the potential for reaching 1 ns timing uncertainty at 1
month with realistic system parameters.

No class-B quantum density-matrix model is available to date, capable of accurately describing coherence and photon correlations within a unified theory.
Here we carry out a density-matrix theoretical approach for generic class-B lasers, and provide closed equations for the photonic and atomic reduced density matrix in the Fock basis of photons.
This model enables the study of few-photon bifurcations and non-classical photon correlations in class-B laser devices, also leveraging quantum descriptions of coherently coupled nanolaser arrays.
