Finite-temperature superfluid depletion of disordered Bose gases
Cord A. Müller
At zero temperature, homogeneous interacting Bose-condensed fluids are entirely superfluid, with remarkable transport properties. A non-superfluid, normal component is induced by f…
Coherent back and forward scattering peaks in the quantum kicked rotor
Gabriel Lemarié, Cord A. Müller, David Guéry-Odelin +1
We propose and analyze an experimental scheme using the quantum kicked rotor to observe the newly-predicted coherent forward scattering peak together with its long-known twin broth…
Josephson relation for disordered superfluids
Cord A. Müller
The Josephson sum rule relates the superfluid density to the condensate order parameter, via the infrared residue of the single-particle Green's function. We establish an effective…
Stability and decay of Bloch oscillations in presence of time-dependent nonlinearity
Christopher Gaul, Elena Díaz, Rodrigo P. A. Lima +2
We consider Bloch oscillations of Bose-Einstein condensates in presence of a time-modulated s-wave scattering length. Generically, interaction leads to dephasing and decay of the w…
Bogoliubov Excitations of Disordered Bose-Einstein Condensates
Christopher Gaul, Cord A. Müller
We describe repulsively interacting Bose-Einstein condensates in spatially correlated disorder potentials of arbitrary dimension. The first effect of disorder is to deform the mean…
One-dimensional Anderson localization in certain correlated random potentials
Pierre Lugan, Alain Aspect, Laurent Sanchez-Palencia +4
We study Anderson localization of ultracold atoms in weak, one-dimensional speckle potentials, using perturbation theory beyond Born approximation. We show the existence of a serie…
