In Situ Coherence Measurements of Scattered Light in Magnetically Trapped Cold Atomic Clouds: Probe-Driven Atomic Dynamics
Amilson R. Fritsch, Hector Letellier, Leonardo Lima da Silva +4
The use of temporal correlations in scattered photons to probe the microscopic dynamics of ultracold quantum gases has emerged as a powerful, minimally destructive approach for in…
On-Sky Single-photon Time resolution of 35 ps with White Rabbit synchronization: towards the measurement of the size of a White Dwarf star
F. Izraelevitch-Patitucci, S. Tolilla, I. Ellafi +7
The IC4Stars (Intensity Correlation for Stars) project aims to measure the diameter of the white dwarf star Sirius B, using Intensity Interferometry. In this work we present our la…
Collective resonance displacement in strongly driven cold atoms
Mateus A. F. Biscassi, Robin Kaiser, Mathilde Hugbart +1
Cold atoms are promising platforms for metrology and quantum computation, yet their many-body dynamics remains largely unexplored. We here investigate Rabi oscillations from optica…
Stellar intensity interferometry in the photon-counting regime
William Guerin, Mathilde Hugbart, Sarah Tolila +5
Stellar intensity interferometry consists in measuring the correlation of the light intensity fluctuations at two telescopes observing the same star. The amplitude of the correlati…
Dimensional Control of the Coherence Time of Scattered Light in Cold Atom Clouds
Ana Cipris, Mateus a F Biscassi, J C C Capella +9
Cold atomic clouds are promising platforms for generating correlated photons, but multiple scattering and associated Doppler broadening limit their temporal coherence. Here we demo…
Phase-contrast imaging of a dense atomic cloud
M. Frometa Fernandez, P. G. Santos Dias, P. H. Nantes Magnani +5
We present the experimental production and characterization of a dense cold atomic cloud of \(^{88}\text{Sr}\) atoms, optimized for the future studies of light transport in highly…
