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. Tolila, 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…
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…
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…
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…
Temporal coherences of atomic chaotic light sources: the Siegert relation and beyond
Martial Morisse, Stuti Joshi, Jaromir Mika +5
Light is characterized by its electric field, yet quantum optics has revealed the importance of monitoring photon-photon correlations at all orders. We here present a comparative s…
Breaking of reciprocity and the Pancharatnam-Berry phase for light scattered by a disordered cold atom cloud
P. H. N. Magnani, P. G. S. Dias, M. Frometa +7
Collective effects on the light scattered by disordered media such as Anderson localization and coherent backscattering critically depend on the reciprocity between interfering opt…
Intensity Interferometry observations of the H envelope of Cas with MéO and a portable telescope
Nolan Matthews, Jean-Pierre Rivet, David Vernet +9
We report on observations of the extended environment of the bright Be star -Cas performed using intensity interferometry measurements within its H emission line. These obser…
From classical to quantum loss of light coherence
Pierre Lassègues, Mateus Antônio Fernandes Biscassi, Martial Morisse +7
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 spo…
Field and intensity correlations: the Siegert relation from stars to quantum emitters
Pierre Lassègues, Mateus Antônio Fernandes Biscassi, Martial Morisse +9
The Siegert relation relates field and intensity temporal correlations. After a historical review of the Siegert relation and the Hanbury Brown and Twiss effect, we discuss the val…
Intensity Interferometry at Calern and beyond: progress report
Nolan Matthews, Jean-Pierre Rivet, Mathilde Hugbart +10
We present the current status of the I2C stellar intensity interferometer used towards high angular resolution observations of stars in visible wavelengths. In these proceedings, w…
Combined spectroscopy and intensity interferometry to determine the distances of the blue supergiants P Cygni and Rigel
E. S. G. de Almeida, Mathilde Hugbart, Armando Domiciano de Souza +10
In this paper we report on spatial intensity interferometry measurements within the H line on two stars: the Luminous Blue Variable supergiant \PCygni\,and the late-type B super…
Mirror-assisted backscattering interferometry to measure the first-order correlation function of the light emitted by quantum scatterers
Pablo Gabriel Santos Dias, Marcia Frometa Fernandez, Pedro Henrique Nantes Magnani +4
We present a new method to obtain the first-order temporal correlation function, , of the light scattered by an assembly of point-like quantum scatterers, or equivalen…

Pierre-Marie Gori, Farrokh Vakili, Jean-Pierre Rivet +6
We propose a new approach, based on the Hanbury Brown and Twiss intensity interferometry, to transform a Cherenkov telescope to its equivalent optical telescope. We show that, base…
Photon-photon Correlations from a Pair of Strongly Coupled Two-Level Emitters
Elnaz Darsheshdar, Mathilde Hugbart, Romain Bachelard +1
We investigate two-color photon correlations in the light emitted by strongly coupled two-level emitters. Spectral filtering allows us to manipulate the collected light statistics…
