• Abstract summary: We report on the realization of large assembled arrays of more than 300 single $87$Rb atoms trapped in optical tweezers in a cryogenic environment. For arrays with $N_rm a=324$ atoms, the assembly process results in defect-free arrays in $sim37%$ of the realizations.

• Abstract: We report on the realization of large assembled arrays of more than 300 single $^{87}$Rb atoms trapped in optical tweezers in a cryogenic environment at $\sim4$~K. For arrays with $N_{\rm a}=324$ atoms, the assembly process results in defect-free arrays in $\sim37\%$ of the realizations. To achieve this high assembling efficiency, we equalize the loading probability of the traps within the array using a closed-loop optimization of the power of each optical tweezers, based on the analysis of the fluorescence time-traces of atoms loaded in the traps.

• On-the-Spot Loading of Single-Atom Traps [0.0]
  We show that increasing the depth of a static, optical dipole trap enables the transition from fast loading on a timescale of $2.1,$s to an extended trap lifetime of $7.9,$s. This method demonstrates an achievable filling ratio of $(79pm2),%$ without the need of rearranging atoms to fill vacant traps.

• Continuous operation of large-scale atom arrays in optical lattices [0.0]
  Scaling the size of assembled neutral-atom arrays trapped in optical lattices or optical tweezers is an enabling step for a number of applications. We show that we can continuously maintain such large arrays by simply reloading atoms that are lost from one cycle to the next. Our approach paves the way towards quantum science with large ordered atomic arrays containing thousands of atoms in continuous operation.

We demonstrate a new paradigm for assembly of atomic arrays, based on a synergistic combination of optical tweezers and cavity-enhanced optical lattices.

  We numerically quantify the performance of the red-rec algorithm, both in the absence and in the presence of loss. We show that the number of traps required to prepare a compact-centered configuration of atoms on a grid with a mean success probability of one half scales as the 3/2 power of the number of desired atoms. The red-rec algorithm admits an efficient implementation that can readily be deployed on real-time control systems.

• 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.

• Preparation of ultra-cold atomic-ensemble arrays using time-multiplexed optical tweezers [0.0]
  We use optical tweezers based on time-multiplexed acousto-optic deflectors to trap ultra-cold cesium atoms in one-dimensional arrays of atomic ensembles. For temperatures between 2.5 $mu$K and 50 nK we study the maximal time between optical tweezer pulses that retains the number of atoms in a single trap. We demonstrate three different protocols for the preparation of atomic-ensemble arrays by transfer from an expanding ultra-cold atomic cloud.
