Extreme-ultraviolet spectroscopy using quantum logic: a feasibility study for the 1S-2S transition in singly-ionized helium
A. Martínez de Velasco, V. P. J. Barbé, E. L. Gründeman +11
Extreme-ultraviolet (XUV) spectroscopy represents an important new direction in precision physics, with potential applications ranging from the metrology of fundamental constants t…
Phase-stabilized UV light at 267 nm through twofold second harmonic generation
Benjamin Kraus, Fabian Dawel, Stephan Hannig +3
Providing phase stable laser light is important to extend the interrogation time of optical clocks towards many seconds and thus achieve small statistical uncertainties. We report…
An Optical Atomic Clock Based on a Highly Charged Ion
Steven A. King, Lukas J. Spieß, Peter Micke +9
Optical atomic clocks are the most accurate measurement devices ever constructed and have found many applications in fundamental science and technology. The use of highly charged i…
New Horizons: Scalar and Vector Ultralight Dark Matter
D. Antypas, A. Banerjee, C. Bartram +123
The last decade has seen unprecedented effort in dark matter model building at all mass scales coupled with the design of numerous new detection strategies. Transformative advances…
Ab initio quantum theory of mass defect and time dilation in trapped-ion optical clocks
V. J. Martínez-Lahuerta, S. Eilers, T. E. Mehlstäubler +2
We derive a Hamiltonian for the external and internal dynamics of an electromagnetically bound, charged two-particle system in external electromagnetic and gravitational fields, in…
On-Line Estimation of Local Oscillator Noise and Optimisation of Servo Parameters in Atomic Clocks
Ian D. Leroux, Nils Scharnhorst, Stephan Hannig +4
For atomic frequency standards in which fluctuations of the local oscillator (LO) frequency are the dominant noise source, we examine the role of the servo algorithm that predicts…
