Elastic scattering of a quantum matter-wave bright soliton on a barrier (2012)
Journal Article

We consider a one-dimensional matter-wave bright soliton, corresponding to the ground bound state of N bosonic particles of mass m having a binary attractive delta potential interaction on the open line. For a full N-body quantum treatment, we derive... Read More about Elastic scattering of a quantum matter-wave bright soliton on a barrier.

Three-photon electromagnetically induced transparency using Rydberg states (2012)

We demonstrate electromagnetically induced transparency in a four-level cascade system where the upper level is a Rydberg state. The observed spectral features are sub-Doppler and can be enhanced due to the compensation of Doppler shifts with AC Star...

Nonlocal quantum superpositions of bright matter-wave solitons and dimers (2012)

The scattering of bright quantum solitons at barrier potentials in one-dimensional geometries is investigated. Such protocols have been predicted to lead to the creation of nonlocal quantum superpositions. The centre-of-mass motion of these bright ma...
