An atomic clock with room-temperature blackbody Stark uncertainty
K. Beloy, N. Hinkley, N. B. Phillips +7
The Stark shift due to blackbody radiation (BBR) is the key factor limiting the performance of many atomic frequency standards, with the BBR environment inside the clock apparatus…
Optical atomic clocks
N. Poli, C. W. Oates, P. Gill +1
In the last ten years extraordinary results in time and frequency metrology have been demonstrated. Frequency-stabilization techniques for continuous-wave lasers and femto-second o…
An atomic clock with instability
N. Hinkley, J. A. Sherman, N. B. Phillips +6
Atomic clocks have been transformational in science and technology, leading to innovations such as global positioning, advanced communications, and tests of fundamental constant va…
Sub-femtosecond absolute timing precision with a 10 GHz hybrid photonic-microwave oscillator
T. M. Fortier, C. W. Nelson, A. Hati +10
We present an optical-electronic approach to generating microwave signals with high spectral purity. By circumventing shot noise and operating near fundamental thermal limits, we d…
High accuracy measure of atomic polarizability in an optical lattice clock
J. A. Sherman, N. D. Lemke, N. Hinkley +4
Despite being a canonical example of quantum mechanical perturbation theory, as well as one of the earliest observed spectroscopic shifts, the Stark effect contributes the largest…
Stability limits of an optical frequency standard based on free Ca atoms
J. A. Sherman, C. W. Oates
We have quantified a short term instability budget for an optical frequency standard based on cold, freely expanding calcium atoms. Such systems are the subject of renewed interest…
