Autor: King, Steven A., Spieß, Lukas J., Micke, Peter, Wilzewski, Alexander, Leopold, Tobias, Benkler, Erik, Lange, Richard, Huntemann, Nils, Surzhykov, Andrey, Yerokhin, Vladimir A., López-Urrutia, José R. Crespo, Schmidt, Piet O.

Publikováno v: Nature 611, 43-47 (2022)

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 ions (HCI) as a new class of references for highest accuracy clocks and

Algorithmic Ground-state Cooling of Weakly-Coupled Oscillators using Quantum Logic

Autor: King, Steven A., Spieß, Lukas J., Micke, Peter, Wilzewski, Alexander, Leopold, Tobias, López-Urrutia, José R. Crespo, Schmidt, Piet O.

Most ions lack the fast, cycling transitions that are necessary for direct laser cooling. In most cases, they can still be cooled sympathetically through their Coulomb interaction with a second, coolable ion species confined in the same potential. If

Sensitivity to New Physics of Isotope Shift Studies using the Coronal Lines of Highly Charged Calcium Ions

Autor: Rehbehn, Nils-Holger, Rosner, Michael K., Bekker, Hendrik, Berengut, Julian C., Schmidt, Piet O., King, Steven A., Micke, Peter, Gu, Ming Feng, Müller, Robert, Surzhykov, Andrey, López-Urrutia, José R. Crespo

Publikováno v: Phys. Rev. A 103, 040801 (2021)

Promising searches for new physics beyond the current Standard Model (SM) of particle physics are feasible through isotope-shift spectroscopy, which is sensitive to a hypothetical fifth force between the neutrons of the nucleus and the electrons of t

Report

A cryogenic radio-frequency ion trap for quantum logic spectroscopy of highly charged ions

Autor: Leopold, Tobias, King, Steven A., Micke, Peter, Bautista-Salvador, Amado, Heip, Jan C., Ospelkaus, Christian, López-Urrutia, José R. Crespo, Schmidt, Piet O.

A cryogenic radio-frequency ion trap system designed for quantum logic spectroscopy of highly charged ions is presented. It includes a segmented linear Paul trap, an in-vacuum imaging lens and a helical resonator. We demonstrate ground state cooling

Report

A self-injection locked DBR laser for laser cooling of beryllium ions

Autor: King, Steven A., Leopold, Tobias, Thekkeppatt, Premjith, Schmidt, Piet O.

We present a simple, robust, narrow-linewidth, frequency-doubled semiconductor laser source suitable for laser cooling and repumping of $^9$Be$^+$ ions. A distributed Bragg reflector (DBR) laser diode operating at 626 nm is self-injection-locked to a
