Towards Quantum Logic Inspired Cooling and Detection for Single (Anti-)Protons

T. Meiners, M. Niemann, A. -G. Paschke +7

We discuss laser-based and quantum logic inspired cooling and detection methods amenable to single (anti-)protons. These would be applicable e.g. in a g-factor based test of CPT in…

Towards Sympathetic Cooling of Single (Anti-)Protons

T. Meiners, M. Niemann, J. Mielke +5

We present methods to manipulate and detect the motional state and the spin state of a single antiproton or proton which are currently under development within the BASE (Baryon Ant…

Towards Sympathetic Laser Cooling and Detection of Single (Anti-)Proton

T. Meiners, M. Niemann, A. -G. Paschke +8

Current experimental efforts to test the fundamental CPT symmetry with single (anti-)protons are progressing at a rapid pace but are hurt by the nonzero temperature of particles an…

Cryogenic Penning-Trap Apparatus for Precision Experiments with Sympathetically Cooled (anti)protons

M. Niemann, T. Meiners, J. Mielke +17

Current precision experiments with single (anti)protons to test CPT symmetry progress at a rapid pace, but are complicated by the need to cool particles to sub-thermal energies. We…

Quantum logic inspired techniques for spacetime-symmetry tests with (anti-)protons

Juan M. Cornejo, Ralf Lehnert, Malte Niemann +9

Cosmological observations as well as theoretical approaches to physics beyond the Standard Model provide strong motivations for experimental tests of fundamental symmetries, such a…

139 GHz UV phase-locked Raman laser system for thermometry and sideband cooling of Be ions in a Penning trap

Johannes Mielke, Julian Pick, Julia A. Coenders +5

We demonstrate phase locking of two ultraviolet laser sources by modulating a fundamental infrared laser with 4th-order sidebands using an electro-optic modulator and phase locking…

Cryogenic Be Penning trap for precision measurements with (anti-)protons

Malte Niemann, Teresa Meiners, Johannes Mielke +4

Cooling and detection schemes using laser cooling and methods of quantum logic can contribute to high precision CPT symmetry tests in the baryonic sector. This work introduces an e…

A highly stable monolithic enhancement cavity for SHG generation in the UV

S. Hannig, J. Mielke, J. A. Fenske +4

We present a highly stable bow-tie power enhancement cavity for critical second-harmonic generation into the UV using a Brewster-cut -BaBO (BBO) nonlinear crystal. The c…
