Experimental determination of the E2-M1 polarizability of the strontium clock transition
Sören Dörscher, Joshua Klose, Sarath Maratha Palli +1
To operate an optical lattice clock at a fractional uncertainty below , one must typically consider not only electric-dipole (E1) interaction between an atom and the latt…
Dynamic decoupling of laser phase noise in compound atomic clocks
Sören Dörscher, Ali Al-Masoudi, Marcin Bober +4
The frequency stability achieved by an optical atomic clock ultimately depends on the coherence of its local oscillator. Even the best ultrastable lasers only allow interrogation t…
Guidelines for developing optical clocks with fractional frequency uncertainty
Moustafa Abdel-Hafiz, Piotr Ablewski, Ali Al-Masoudi +42
There has been tremendous progress in the performance of optical frequency standards since the first proposals to carry out precision spectroscopy on trapped, single ions in the 19…
A high-performance optical lattice clock based on bosonic atoms
Stefano Origlia, Mysore Srinivas Pramod, Stephan Schiller +9
Optical lattice clocks with uncertainty and instability in the -range and below have so far been demonstrated exclusively using fermions. Here, we demonstrate a bosonic o…
Lattice-induced photon scattering in an optical lattice clock
Sören Dörscher, Roman Schwarz, Ali Al-Masoudi +3
We investigate scattering of lattice laser radiation in a strontium optical lattice clock and its implications for operating clocks at interrogation times up to several tens of sec…
