The scattering of 1D matter wave bright solitons on attractive potentials enables one to populate bound states, a feature impossible with noninteracting wave packets. Compared to noninteracting states, the populated states are renormalized by the attractive interactions between atoms and keep the same topology. This renormalization can even transform a virtual state into a bound state. By switching off adiabatically the interactions, the trapped wave packets converge towards the true… 

Quantum tunneling dynamics of an interacting Bose-Einstein condensate through a Gaussian barrier

Particle-wave duality in quantum tunneling of a bright soliton.

It is demonstrated that the formation of a localized bound state is essential to describe such inelastic collisions, showing a nontrivial nonlinear effect on the quantum transportation of a bright soliton.

Bright Bose-Einstein gap solitons of atoms with repulsive interaction.

The first experimental observation of bright matter wavesolitons for 87Rb atoms with repulsive atom-atom interaction is reported, allowing the systematic investigation of gap solitons.

Realization of a distributed Bragg reflector for propagating guided matter waves.

It is shown that the Gaussian envelope of the optical lattice has a major influence on the properties of the reflector and gives rise to multiple reflections of the wave packet between two symmetric locations where Bragg reflection occurs.

Coherent Evolution of Bouncing Bose-Einstein Condensates

We investigate the evolution of Bose-Einstein condensates falling under gravity and bouncing off a mirror formed by a far-detuned sheet of light. After reflection, the atomic density profile develops

Watching dark solitons decay into vortex rings in a Bose-Einstein condensate.

We have created spatial dark solitons in two-component Bose-Einstein condensates in which the soliton exists in one of the condensate components and the soliton nodal plane is filled with the second

Nonlinear optics.

In this method, non-linear susceptibility tensors are introduced which relate the induced dipole moment to a power series expansion in field strengths and the various experimental observations are described and interpreted in terms of this formalism.

Collisions of matter-wave solitons

Atomic matter waves provide a controllable platform for studying the behaviour of solitons. In a lithium condensate, a characterization of the dynamics of collisions between solitons reveals a

Waveguide atom beam splitter for laser-cooled neutral atoms.

A laser-cooled neutral-atom beam from a low-velocity intense source is split into two beams while it is guided by a magnetic-field potential. We generate our multimode beam-splitter potential with
