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…
Optical coherent manipulation of alkaline-earth circular Rydberg states
Andrea Muni, Léa Lachaud, Angelo Couto +5
Rydberg atoms are ideal tools for quantum technologies. Due to their large size, their dipole-dipole interaction at micrometer-scale distances and their coupling to external fields…
Progress towards a matter wave interferometer for inertial sensing with non-destructive monitoring of Bloch oscillations
D. Rivero, C. Beli Silva, M. A. Moreno Armijo +6
We report on our progress in the construction of a continuous matter-wave interferometer for inertial sensing via the non-destructive observation of Bloch oscillations. At the pres…
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…
Preparation of Long-Lived, Non-Autoionizing Circular Rydberg States of Strontium
R. C. Teixeira, A. Larrouy, A. Muni +5
Alkaline earth Rydberg atoms are very promising tools for quantum technologies. Their highly excited outer electron provides them with the remarkable properties of Rydberg atoms an…
Mollow triplet in cold atoms
Luis Ortiz-Gutiérrez, Raul Teixeira, Aurélien Eloy +4
In this paper, we measure the spectrum of light scattered by a cold atomic cloud driven by a strong laser beam. The experimental technique is based on heterodyne spectroscopy coupl…
Comparison between 403 nm and 497 nm repumping schemes for strontium magneto-optical traps
P H Moriya, M O Araújo, F Todão +5
The theoretical description of the external degrees of freedom of atoms trapped inside a magneto-optical trap (MOT) often relies on the decoupling of the evolution of the internal…
Mirror-assisted coherent backscattering from the Mollow sidebands
N. Piovella, R. Celistrino Teixeira, R. Kaiser +2
In front of a mirror, the radiation of weakly driven large disordered clouds presents an interference fringe in the backward direction, on top of an incoherent background. Although…
Injection locking of a low cost high power laser diode at 461 nm
C. J. H. Pagett, P. H. Moriya, R. Celistrino Teixeira +3
Stable laser sources at 461 nm are important for optical cooling of strontium atoms. In most existing experiments this wavelength is obtained by frequency doubling infrared lasers,…
Microwave probes Dipole Blockade and van der Waals Forces in a Cold Rydberg Gas
R. Celistrino Teixeira, C. Hermann-Avigliano, Thanh Long Nguyen +5
We show that microwave spectroscopy of a dense Rydberg gas trapped on a superconducting atom chip in the dipole blockade regime reveals directly the dipole-dipole many-body interac…
