Abstract summary: Light is a precious tool to probe matter, as it captures microscopic and macroscopic information on the system. We report on the transition from a thermal (classical) to a spontaneous emission (quantum) mechanism for the loss of light coherence from a macroscopic atomic cloud.

Abstract: Light is a precious tool to probe matter, as it captures microscopic and macroscopic information on the system. We here report on the transition from a thermal (classical) to a spontaneous emission (quantum) mechanism for the loss of light coherence from a macroscopic atomic cloud. The coherence is probed by intensity-intensity correlation measurements realized on the light scattered by the atomic sample, and the transition is explored by tuning the balance between thermal coherence loss and spontaneous emission via the pump strength. Our results illustrate the potential of cold atom setups to investigate the classical-to-quantum transition in macroscopic systems.

Limits for coherent optical control of quantum emitters in layered materials [49.596352607801784]
coherent control of a two-level system is among the most essential challenges in modern quantum optics. We use a mechanically isolated quantum emitter in hexagonal boron nitride to explore the individual mechanisms which affect the coherence of an optical transition under resonant drive. New insights on the underlying physical decoherence mechanisms reveals a limit in temperature until which coherent driving of the system is possible.

Quantum Effects on the Synchronization Dynamics of the Kuramoto Model [62.997667081978825]
We show that quantum fluctuations hinder the emergence of synchronization, albeit not entirely suppressing it. We derive an analytical expression for the critical coupling, highlighting its dependence on the model parameters.

Correlated steady states and Raman lasing in continuously pumped and probed atomic ensembles [68.8204255655161]
We consider an ensemble of Alkali atoms that are continuously optically pumped and probed. Due to the collective scattering of photons at large optical depth, the steady state of atoms does not correspond to an uncorrelated tensor-product state. We find and characterize regimes of Raman lasing, akin to the model of a superradiant laser.

Superradiant detection of microscopic optical dipolar interactions [4.481048642352541]
We demonstrate a method to perform background-free'' detection of the microscopic optical dynamics in a laser-cooled atomic ensemble. This is made possible by transiently suppressing the macroscopic optical propagation over a substantial time. We apply this technique to unveil and precisely characterize a density-dependent, microscopic dipolar dephasing effect.

These allow new alternatives toward the design of robust mechanisms for quantum information purposes.
