Controlling symmetry and localization with an artificial gauge field in a disordered quantum system
Autor: Clément Hainaut, Isam Manai, Jean-François Clément, Jean Claude Garreau, Pascal Szriftgiser, Gabriel Lemarié, Nicolas Cherroret, Dominique Delande, Radu Chicireanu
Publikováno v: Nature Communications, Vol 9, Iss 1, Pp 1-9 (2018)
Periodically kicked rotors are useful in exploring localization phenomenon. Here the authors use ultracold Cs atoms kicked by short laser pulses and show that the periodic modulation results into interference signals as a signature of weak and strong

Experimental realization of an ideal Floquet disordered system

Publikováno v: New Journal of Physics, Vol 21, Iss 3, p 035008 (2019)
The atomic Quantum Kicked Rotor (QKR) is an outstanding ‘quantum simulator’ for the exploration of transport in disordered quantum systems. Here we study experimentally the phase-shifted QKR , which we show to display properties close to an ideal

Phase diagram of the anisotropic Anderson transition with the atomic kicked rotor: theory and experiment

Publikováno v: New Journal of Physics, Vol 15, Iss 6, p 065013 (2013)
We realize experimentally a cold-atom system, the quasiperiodic kicked rotor, equivalent to the three-dimensional Anderson model of disordered solids where the anisotropy between the x direction and the y – z plane can be controlled by adjusting an

Spectral description of the dynamics of ultracold interacting bosons in disordered lattices
Autor: Benoît Vermersch, Jean Claude Garreau
Publikováno v: New Journal of Physics, Vol 15, Iss 4, p 045030 (2013)
We study the dynamics of a nonlinear one-dimensional disordered system from a spectral point of view. The spectral entropy and the Lyapunov exponent are extracted from the short-time dynamics, and are shown to give a pertinent characterization of the

Localization properties of the asymptotic density distribution of a one-dimensional disordered system
Autor: Clément Hainaut, Jean-François Clément, Pascal Szriftgiser, Jean Claude Garreau, Adam Rançon, Radu Chicireanu
Publikováno v: Eur.Phys.J.D
Eur.Phys.J.D, 2022, 76 (6), pp.103. ⟨10.1140/epjd/s10053-022-00426-2⟩
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 states are localized, implying that the distribution of an initially narr

International audience; We describe a compact and versatile multi-frequency laser system for laser-cooling potassium atoms, by frequency doubling a fiber-optic telecom beam ($\simeq 1534$ or $1540$~nm). Low-power fiber-based telecom lasers and compon

Analog quantum simulation of the spinor-four Dirac equation with an artificial gauge field

Physical Review A, 2020, 101 (5), ⟨10.1103/PhysRevA.101.053608⟩
A two-dimensional spatially and temporally modulated Wannier-Stark system of ultracold atoms in optical lattices is shown to mimic the behavior of a Dirac particle. Suitable additional modulations generate an artificial gauge field which simulates a

Bogoliubov excitations in the quasiperiodic kicked rotor: Stability of a kicked condensate and the quasi–insulator-to-metal transition
Autor: Dominique Delande, Jean Claude Garreau, Benoît Vermersch

Physical Review A, 2020, 101 (5), ⟨10.1103/PhysRevA.101.053625⟩
We study the dynamics of a Bose-Einstein condensate in the quasiperiodic kicked rotor described by a Gross-Pitaevskii equation with periodic boundary conditions. As the interactions are increased, Bogoliubov excitations appear and deplete the condens
