Coordinated international comparisons between optical clocks connected via fiber and satellite links
Thomas Lindvall, Marco Pizzocaro, Rachel M. Godun +62
Optical clocks provide ultra-precise frequency references that are vital for international metrology as well as for tests of fundamental physics. To investigate the level of agreem…
Deterministic preparation of a dual-species two-ion crystal
Maximilian J. Zawierucha, Till Rehmert, Jonas Keller +3
The demand for efficient preparation methods for dual-species ion crystals is rapidly expanding across quantum technology and fundamental physics applications with trapped ions. We…
Controlling systematic frequency uncertainties at the level in linear Coulomb crystals
J. Keller, T. Burgermeister, D. Kalincev +5
Trapped ions are ideally suited for precision spectroscopy, as is evident from the remarkably low systematic uncertainties of single-ion clocks. The major weakness of these clocks…
Symmetry Breaking and Topological Defect Formation in Ion Coulomb Crystals
Karsten Pyka, Jonas Keller, Heather L. Partner +9
Symmetry breaking phase transitions play an important role in nature. When a system traverses such a transition at a finite rate, its causally disconnected regions choose the new b…
Linear Paul trap design for an optical clock with Coulomb crystals
Norbert Herschbach, Karsten Pyka, Jonas Keller +1
We report on the design of a segmented linear Paul trap for optical clock applications using trapped ion Coulomb crystals. For an optical clock with an improved short-term stabilit…
