Bogoliubov excitations in the quasiperiodic kicked rotor: stability of a kicked condensate and the quasi-insulator-metal transition
Benoit Vermersch, Dominique Delande, Jean Claude Garreau
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 interaction…
Emergence of nonlinear behavior in the dynamics of ultracold bosons
Benoit Vermersch, Jean Claude Garreau
We study the evolution of a system of interacting ultracold bosons, which presents nonlinear, chaotic, behaviors in the limit of very large number of particles. Using the spectral…
Anderson transition of Bogoliubov quasiparticles in the quasiperiodic kicked rotor
Benoit Vermersch, Dominique Delande, Jean Claude Garreau
We study the dynamics of Bogoliubov excitations of a Bose-Einstein condensate in the quasiperiodic kicked rotor. In the weakly interacting regime, the condensate is stable and both…
How nonlinear interactions challenge the three-dimensional Anderson transition
Nicolas Cherroret, Benoît Vermersch, Jean Claude Garreau +1
In disordered systems, our present understanding of the Anderson transition is hampered by the possible presence of interactions between particles. We demonstrate that in boson gas…
Spectral description of the dynamics of ultracold interacting bosons in disordered lattices
Benoît Vermersch, Jean Claude Garreau
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 ti…
Decoherence effects in the dynamics of interacting ultracold bosons in disordered lattices
Benoît Vermersch, Jean-Claude Garreau
We study the interplay between disorder, interactions and decoherence induced by spontaneous emission process. Interactions are included in the Anderson model via a mean-field appr…
Sensitivity to the initial state of interacting ultracold bosons in disordered lattices
Benoît Vermersch, Jean-Claude Garreau
We study the dynamics of a nonlinear one-dimensional disordered system obtained by coupling the Anderson model with the Gross-Pitaevskii equation. An analytical model provides us w…
