Coherent backscattering of ultracold atoms

F Jendrzejewski, K Müller, J Richard, A Date… - Physical Review Letters, 2012 - APS
We report on the direct observation of coherent backscattering (CBS) of ultracold atoms in a
quasi-two-dimensional configuration. Launching atoms with a well-defined momentum in a …

How nonlinear interactions challenge the three-dimensional Anderson transition

N Cherroret, B Vermersch, JC Garreau, D Delande - Physical Review Letters, 2014 - APS
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 …

Coherent backscattering in Fock space: a signature of quantum many-body interference in interacting bosonic systems

T Engl, J Dujardin, A Argüelles, P Schlagheck… - Physical Review Letters, 2014 - APS
We predict a generic signature of quantum interference in many-body bosonic systems
resulting in a coherent enhancement of the average return probability in Fock space. This …

Nonautonomous matter waves in a waveguide

Z Yan, XF Zhang, WM Liu - Physical Review A—Atomic, Molecular, and Optical …, 2011 - APS
We present a physical model that describes the transport of Bose-Einstein-condensed atoms
from a reservoir to a waveguide. By using the similarity and Möbius transformations, we …

Coherent multiple scattering of out-of-equilibrium interacting Bose gases

N Cherroret, T Scoquart, D Delande - Annals of Physics, 2021 - Elsevier
We review recent theoretical and experimental progresses in the coherent multiple
scattering of weakly interacting disordered Bose gases. These systems have allowed, in the …

Coherent backscattering of ultracold matter waves: Momentum space signatures

N Cherroret, T Karpiuk, CA Müller, B Grémaud… - Physical Review A …, 2012 - APS
Using analytical and numerical methods, it is shown that the momentum distribution of a
matter wave packet launched in a random potential exhibits a pronounced coherent …

Quench dynamics of a weakly interacting disordered Bose gas in momentum space

T Scoquart, T Wellens, D Delande, N Cherroret - Physical Review Research, 2020 - APS
We study theoretically the out-of-equilibrium dynamics in momentum space of a weakly
interacting disordered Bose gas launched with a finite velocity. In the absence of …

Stationary waves on nonlinear quantum graphs: General framework and canonical perturbation theory

S Gnutzmann, D Waltner - Physical Review E, 2016 - APS
In this paper we present a general framework for solving the stationary nonlinear
