Scattering of bright solitons by disorder

April 2016: The CNRS group is studying experimentally an intriguing aspect of one-dimensional transport, namely that of bright solitons in attractive-interacting bosonic 1D gases. The soliton size has been precisely characterized as a function of the scattering length through three-body losses. Close to the collapse threshold, the solitons are shown to be strongly bound. The... Continue Reading →

Many-body localization with random interactions

February 2017: A theoretical investigation by UJ has demonstrated that not only random potentials but also random interactions can give rise to MBL. The study focused on ultracold bosons in one-dimensional lattices under interactions that are random from site to site (distributed uniformly between 0 and U). Contrary to previously studied models that show Anderson... Continue Reading →

Mott transition in a shallow periodic potential

January 2016: A consortium between the CNRS and LENS groups and well as the ICFO group report the first quantitative determination of the superfluid to Mott insulator transition for strongly-interacting one-dimensional bosons in arbitrary weak periodic potentials. Theoretical calculations and direct experimental measurements are in excellent agreement and show a significant shift of the transition... Continue Reading →

QUIC kick off

March 1st, 2015, is the official kick off of the QUIC project. There are four years of exciting research ahead! The QUIC project has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement No 641122.
