Localization properties of the asymptotic density distribution of a one-dimensional disordered system
Clément Hainaut, Jean-François Clément, Pascal Szriftgiser +3
Anderson localization is the ubiquitous phenomenon of inhibition of transport of classical and quantum waves in a disordered medium. In dimension one, it is well known that all sta…
Multi-frequency telecom fibered laser system for potassium laser cooling
Charbel Cherfan, Maxime Denis, Denis Bacquet +7
We describe a compact and versatile multi-frequency laser system for laser-cooling potassium atoms, by frequency doubling a fiber-optic telecom beam ( or ~nm). L…
Acetylene-based frequency stabilization of a laser system for potassium laser cooling
Charbel Cherfan, Isam Manai, Samir Zemmouri +4
We demonstrate a laser frequency stabilization technique for laser cooling of Potassium atoms, based on saturated absorption spectroscopy in the C-Band optical telecommunication wi…
Experimental realization of an ideal Floquet disordered system
Clément Hainaut, Adam Rançon, Jean-François Clément +5
The atomic Quantum Kicked Rotor is an outstanding "quantum simulator" for the exploration of transport in disordered quantum systems. Here we study experimentally the phase-shifted…
Experimental observation of time singularity in classical-to-quantum chaos transition
Clément Hainaut, Ping Fang, Adam Rançon +5
The emergence of chaotic phenomena in a quantum system has long been an elusive subject. Experimental progresses in this subject have become urgently needed in recent years, when c…
Ratchet Effect in the Quantum Kicked Rotor and its Destruction by Dynamical Localization
Clément Hainaut, Adam Rançon, Jean-François Clément +4
We study experimentally a quantum kicked rotor with broken parity symmetry, supporting a ratchet effect due to the presence of a classical accelerator mode. We show that the short-…
Controlling symmetry and localization with an artificial gauge field in a disordered quantum system
Clément Hainaut, Isam Manai, Jean-François Clément +6
Anderson localization, the absence of diffusion in disordered media, draws its origins from the destructive interference between multiple scattering paths. The localization propert…
Return to the Origin as a Probe of Atomic Phase Coherence
Clément Hainaut, Isam Manai, Radu Chicireanu +7
We report on the observation of the coherent enhancement of the return probability ("enhanced return to the origin" , ERO) in a periodically kicked cold-atom gas. By submitting an…
Experimental Observation of Two-Dimensional Anderson Localization with the Atomic Kicked Rotor
Isam Manai, Jean-François Clément, Radu Chicireanu +4
Dimension 2 is expected to be the lower critical dimension for Anderson localization in a time reversal-invariant disordered quantum system. Using an atomic quasiperiodic kicked ro…
Phase diagram of the Anderson transition with atomic matter waves
Matthias Lopez, Jean-François Clément, Gabriel Lemarié +3
We realize experimentally a cold atom system equivalent to the 3D Anderson model of disordered solids where the anisotropy can be controlled by adjusting an experimentally accessib…
Experimental Test of Universality of the Anderson Transition
Matthias Lopez, Jean-François Clément, Pascal Szriftgiser +2
We experimentally test the universality of the Anderson three dimensional metal-insulator transition. Nine sets of parameters controlling the microscopic details of this second ord…
Atomic Dipole Traps with Amplified Spontaneous Emission: A Proposal
Jean-François Clément, Véronique Zehnlé, Jean Claude Garreau +1
We propose what we believe to be a novel type of optical source for ultra-cold atomic Far Off-Resonance optical-dipole Traps (FORTs). The source is based on an Erbium Amplified Spo…
All-optical runaway evaporation to Bose-Einstein condensation
Jean-Francois Clément, Jean-Philippe Brantut, Martin Robert De Saint Vincent +4
We demonstrate runaway evaporative cooling directly with a tightly confining optical dipole trap and achieve fast production of condensates of 1.5x10^5 87Rb atoms. Our scheme is ch…
Dark Optical Lattice of Ring Traps for Cold Atoms
Emmanuel Courtade, Olivier Houde, Jean-François Clément +2
We propose a new geometry of optical lattice for cold atoms, namely a lattice made of a 1D stack of dark ring traps. It is obtained through the interference pattern of a standard G…
I.C.E.: a Transportable Atomic Inertial Sensor for Test in Microgravity
Robert A. Nyman, Gael Varoquaux, Fabien Lienhart +10
We present our the construction of an atom interferometer for inertial sensing in microgravity, as part of the I.C.E. (\textit{Interférométrie Cohérente pour l'Espace}) collaborati…
