• Abstract summary: Current experiments with single (anti)protons to test CPT symmetry progress are complicated by the need to cool particles to sub-thermal energies. We describe a cryogenic Penning-trap setup for $9$Be$+$ ions designed to allow coupling of single (anti)protons to laser-cooled atomic ions for sympathetic cooling and quantum logic spectroscopy.

• Abstract: 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 describe a cryogenic Penning-trap setup for $^9$Be$^+$ ions designed to allow coupling of single (anti)protons to laser-cooled atomic ions for sympathetic cooling and quantum logic spectroscopy. We report on trapping and laser cooling of clouds and single $^9$Be$^+$ ions. We discuss prospects for a microfabricated trap to allow coupling of single (anti)protons to laser-cooled $^9$Be$^+$ ions for sympathetic laser cooling to sub-mK temperatures on ms time scales.

• Laser Scheme for Doppler Cooling of the Hydroxyl Cation (OH$^+$) [0.0]
  We report on a cycling scheme for Doppler cooling of trapped OH$+$ ions using transitions between the electronic ground state $X3Sigma-$ and the first excited triplet state $A3Pi$. We have found that coupling into other electronic states is strongly suppressed, and have calculated the number of photon scatterings required to cool OH$+$ to a temperature where Raman sideband cooling can take over.

  We experimentally demonstrate how to generate a state in condensed matter at moderate cryogenic temperatures. This state is then used to efficiently remove microwave photons from a cavity. Such an "anti-maser" device could be extremely beneficial for applications that would normally require cooling to millikelvin temperatures.

• Quantum Control of Atom-Ion Charge Exchange via Light-induced Conical Intersections [66.33913750180542]
  Conical intersections are crossing points or lines between two or more adiabatic electronic potential energy surfaces. We predict significant or measurable non-adiabatic effects in an ultracold atom-ion charge-exchange reaction. In the laser frequency window, where conical interactions are present, the difference in rate coefficients can be as large as $10-9$ cm$3$/s.

• Quantum density matrix theory for a laser without adiabatic elimination of the population inversion: transition to lasing in the class-B limit [62.997667081978825]
  No class-B quantum density-matrix model is available to date, capable of accurately describing coherence and photon correlations within a unified theory. Here we carry out a density-matrix theoretical approach for generic class-B lasers, and provide closed equations for the photonic and atomic reduced density matrix in the Fock basis of photons. This model enables the study of few-photon bifurcations and non-classical photon correlations in class-B laser devices, also leveraging quantum descriptions of coherently coupled nanolaser arrays.

• Collimated versatile atomic beam source with alkali dispensers [56.73298876206697]
  Alkali metal dispensers have become an indispensable tool in the production of atomic vapors for magnetometry, alkali vapor cell clocks, and laser cooling experiments. We present an integrated rubidium dispenser collimating device with a thickness of only 2 mm that produces a beam of atoms traveling primarily in the forward direction. Our integrated dispenser collimator will particularly be useful in integrated photonics and cavity QED on chip, where a localized, directed source of Rb vapor in small quantities is needed.

  We investigate the production of all-optical $39$K Bose-Einstein condensates with different scattering lengths using a Feshbach resonance near $33$ G. We are able to produce fully condensed ensembles with $5.8times104$ atoms within $850$ ms evaporation time at a scattering length of $232. Based on our findings we describe routes towards high-flux sources of ultra-cold potassium for inertial sensing.

• Algorithmic Ground-state Cooling of Weakly-Coupled Oscillators using Quantum Logic [52.77024349608834]
  We introduce a novel algorithmic cooling protocol for transferring phonons from poorly- to efficiently-cooled modes. We demonstrate it experimentally by simultaneously bringing two motional modes of a Be$+$-Ar$13+$ mixed Coulomb crystal close to their zero-point energies. We reach the lowest temperature reported for a highly charged ion, with a residual temperature of only $Tlesssim200mathrmmu K$ in each of the two modes.

• Robust dynamical exchange cooling with trapped ions [0.0]
  We investigate theoretically the possibility for robust and fast cooling of a trapped atomic ion by transient interaction with a pre-cooled ion. The transient coupling is achieved through dynamical control of the ions' equilibrium positions. For settings appropriate to a currently operational trap in our laboratory, we find that robust performance could be achieved down to $6.3$ motional cycles.
