Fundamental Limits of Large Momentum Transfer in Optical Lattices
Ashkan Alibabaei, Patrik Mönkeberg, Florian Fitzek +5
Large-momentum-transfer techniques are instrumental for the next generation of atom interferometers as they significantly improve their sensitivity. State-of-the-art implementation…
Entanglement-enhanced optical ion clock
Kai Dietze, Lennart Pelzer, Ludwig Krinner +11
Entangled states hold the promise of improving the precision and accuracy of quantum sensors. We experimentally demonstrate that spectroscopy of an optical clock transition using e…
Diffraction phase-free Bragg atom interferometry
Víctor J. Martínez-Lahuerta, Jan-Niclas Kirsten-Siemß, Klemens Hammerer +1
Bragg Diffraction of matter waves is an established technique used in the most accurate quantum sensors. It is also the method of choice to operate large-momentum-transfer, high-se…
Identification of highly-forbidden optical transitions in highly charged ions
Shuying Chen, Lukas J. Spieß, Alexander Wilzewski +6
Optical clocks represent the most precise experimental devices, finding application in fields spanning from frequency metrology to fundamental physics. Recently, the first highly c…
Large-momentum-transfer atom interferometers with rad-accuracy using Bragg diffraction
Jan-Niclas Siemß, Florian Fitzek, Christian Schubert +3
Large-momentum-transfer~(LMT) atom interferometers using elastic Bragg scattering on light waves are among the most precise quantum sensors to date. To advance their accuracy from…
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…
