Title: A COLD-ATOM CLOCK BASED ON COHERENT POPULATION TRAPPING
Published: November 26, 2012
Abstract: A compact cold-atom clock based on coherent population trapping is being developed. The clock aims to ultimately achieve a timing uncertainty of a few nanoseconds per day. Here we present an initial evaluation of the three main systematic frequency shifts - the first-order Doppler shift, the light shift, and the Zeeman shift. Planned steps to reduce the size of these shifts will also be presented.
