Dense atomic clouds represent an interesting platform for studying collective effects, such as super- and subradiance. On the other hand, the correlated emission and absorption of entangled photons has important applications in quantum technologies, in particular, quantum communication protocols. Generally, twin photons are emitted (or absorbed) by single atoms exploiting an atomic multil…
In this project, we will investigate the role of dimensionality and polarization in the scattering of light by point particles. The panel of skills of the participants makes it possible to study light scattering in 10 (optical cavity of Prof. Courteille), 20 (plasmonic structures of Prof. Guimarães) and 3D (magneto-optical traps of Prof. Kaiser). The dimensionality of the system is a crit…
This proposal aims at turning quantum sensor technology into reality. Ahead of the anticipated quantum revolution in commercial applications, the proposal will set up a research consortium working on two specific areas of research: (i) Analysis and implementation of new ideas for quantum sensors based on cold atoms interacting with optical cavities and investigations for the first dual-us…

This master's project aims to study the scattering of light by a dense sample of cold strontium atoms. Specifically, this project aims to implement a measurement of the electric field of light transmitted through a dense and disordered atomic sample. The measurement of the electric field will extend the regime of parameters for which we can characterize the true optical density of the clo…

Today's most accurate inertial sensors employ atomic interferometry realized by splitting and recombining matter wave trajectories via sequences of laser-pulses. The collective atomic spin states generated during the pulses are subject to intrinsic quantum projection noise, which limits the interferometric resolution for a given atom number and integration time. Novel protocols, however, …
The behavior of the light scattering in 3D disordered samples of mean free path smaller than one wavelength is a long-standing open question. The several tentative measurements for the Anderson localization of light in this regime showed inconclusive, and recent theoretical work questioned the emergence of the phenomena. Understanding the light transport properties in dense media, apart f…
Today's most accurate inertial sensors are based on atomic interferometry. The objective of this project is to study, theoretically and experimentally, schemes of collective interaction between cold atoms and light in optical cavities in view of creating non-trivial collective spin states. We will investigate the potential of weakly entangled spin-squeezed states for improved quantum sens…

Quantum-correlated systems lie at the core of modern quantum information technologies. For quantum sensing applications, cold atomic ensembles represent an ideal platform, where strong correlations can be engineered through their interaction with a single light mode stored in an optical cavity. In recent years, the group led by Prof. Ph. Courteille at the Instituto de Física de São Carlos…
Non-classical light sources, such as single photons and entangled photon pairs, are essential for quantum computing, secure quantum communication, and precision metrology. Traditional methods, while effective, often fail to produce light with the spectral properties needed for integration with systems like quantum memories. Recent breakthroughs have shown that atomic ensembles can generat…
The objective of this research project is to study the eminent role that optical cavities can play in the emergence of collective effects and quantum correlations in atomic many-body systems. Superradiant enhancement of the decay of ultranarrow clock transitions in atoms resonantly driven inside optical cavities will provide next generation atomic clocks with orders of magnitude higher pr…
