• Abstract: We experimentally demonstrate a cavity-based detection scheme for a cold atomic ensemble with a radiatively open transition. Our method exploits the collective strong coupling of atoms to the cavity mode, which results in off-resonant probing of the atomic ensemble, leading to a dramatic reduction in losses from the detection cycle. We then show the viability of this frequency measurement for detecting a small number of atoms and molecules by theoretical modelling. Compared with the most commonly used fluorescence method, we show that the cavity-based scheme allows rapid and prolonged detection of the system's evolution with minimal destruction.

  Out-of-time-ordered correlators (OTOCs) have emerged as powerful tools for diagnosing quantum chaos and information scrambling. We investigate the spectral decomposition of OTOCs in open quantum systems using the dissipative modified kicked rotator (DMKR) as a paradigmatic model. Our results provide a quantitative framework for understanding OTOCs in dissipative quantum systems and suggest new avenues for experimental exploration in open quantum platforms.

• In-situ measurements of light diffusion in an optically dense atomic ensemble [0.0]
  This study introduces a novel method to investigate in-situ light transport within optically thick ensembles of cold atoms. A method for creating an optical excitation at the center of a large atomic cloud is demonstrated. In conditions where the cloud size is significantly larger than the transport mean free path, a diffusive regime is identified.

• Collectively enhanced Ramsey readout by cavity sub- to superradiant transition [0.0]
  We experimentally confirm a minimum threshold for superradiant emission on a narrow optical transition. A $pi/2$-pulse places the atoms in a subradiant state, protected from collective cavity decay. The scheme is a fundamentally new approach to atomic state readout characterized by its speed, simplicity, and high sensitivity.

• Cavity Sub- and Superradiance Enhanced Ramsey Spectroscopy [0.0]
  Ramsey spectroscopy in large, dense ensembles of ultra-cold atoms trapped in optical lattices suffers from dipole-dipole interaction induced shifts and collective superradiance limiting its precision and accuracy. We propose a novel geometry implementing fast signal readout with minimal heating for large atom numbers at lower densities via an optical cavity operated in the weak single atom but strong collective coupling regime.

  We propose and investigate a scheme based on Markovian feedback control that allows for the preparation of single targeted eigenstates of a system of bosonic atoms in a one-dimensional optical lattice with high fidelity. It can be used for in-situ cooling the interacting system without particle loss, both for weak and strong interactions, and for experimentally preparing and probing individual excited eigenstates.

  We propose applying time-dependent photo-emission spectroscopy, an established tool in solid state systems, in cold atom quantum simulators. We show in exact diagonalization simulations of the one-dimensional $t-J$ model that the spinons start to populate previously unoccupied states in an effective band structure. The dependence of the spectral function on the time after the pump pulse reveals collective interactions among spinons.
