Al'tshuler-Aronov-Spivak oscillations of bosonic matter-wave beams in the presence of interaction
Renaud Chrétien, Josef Rammensee, Julien Dujardin +2
We theoretically study the propagation of a guided atom laser across an Aharonov-Bohm ring which is exposed to a synthetic gauge field. The presence of disorder within the ring giv…
Coherent backscattering in the Fock space of ultracold bosonic atoms
Peter Schlagheck, Julien Dujardin
We present numerical evidence for the occurrence of coherent backscattering in the Fock space of a small disordered Bose-Hubbard system consisting of four sites and containing five…
Breakdown of Anderson localization in the transport of Bose-Einstein condensates through one-dimensional disordered potentials
Julien Dujardin, Thomas Engl, Peter Schlagheck
We study the transport of an interacting Bose--Einstein condensate through a 1D correlated disorder potential. We use for this purpose the truncated Wigner method, which is, as we…
Describing many-body bosonic waveguide scattering with the truncated Wigner method
Julien Dujardin, Thomas Engl, Juan Diego Urbina +1
We consider quasi-stationary scattering of interacting bosonic matter waves in one-dimensional waveguides, as they arise in guided atom lasers. We show how the truncated Wigner (tW…
Elastic and inelastic transmission in guided atom lasers: a truncated Wigner approach
Julien Dujardin, Arturo Argüelles, Peter Schlagheck
We study the transport properties of an ultracold gas of Bose-Einstein condensate that is coupled from a magnetic trap into a one-dimensional waveguide. Our theoretical approach to…
A study of one-dimensional transport of Bose-Einstein condensates using exterior complex scaling
Julien Dujardin, Alejandro Saenz, Peter Schlagheck
We numerically investigate the one-dimensional transport of Bose-Einstein condensates in the context of guided atom lasers using a mean-field description of the condensate in terms…
Coherent Backscattering in Fock Space: a Signature of Quantum Many-Body Interference in Interacting Bosonic Systems
Thomas Engl, Julien Dujardin, Arturo Argüelles +3
We predict a generic manifestation of quantum interference in many-body bosonic systems resulting in a coherent enhancement of the average return probability in Fock space. This en…
