Critical Velocity and Dissipation of an ultracold Bose-Fermi Counterflow
Marion Delehaye, Sébastien Laurent, Igor Ferrier-Barbut +3
We study the dynamics of counterflowing bosonic and fermionic lithium atoms. First, by tuning the interaction strength we measure the critical velocity vc of the system in the BEC-…
Observing the Rosensweig instability of a quantum ferrofluid
Holger Kadau, Matthias Schmitt, Matthias Wenzel +4
Ferrofluids show unusual hydrodynamic effects due to the magnetic nature of their constituents. For increasing magnetization a classical ferrofluid undergoes a Rosensweig instabili…
Emergence of chaotic scattering in ultracold Er and Dy
T. Maier, H. Kadau, M. Schmitt +13
We show that for ultracold magnetic lanthanide atoms chaotic scattering emerges due to a combination of anisotropic interaction potentials and Zeeman coupling under an external mag…
Broad universal Feshbach resonances in the chaotic spectrum of Dysprosium atoms
Thomas Maier, Igor Ferrier-Barbut, Holger Kadau +6
We report on the observation of weakly-bound dimers of bosonic Dysprosium with a strong universal s-wave halo character, associated with broad magnetic Feshbach resonances. These s…
Universal Loss Dynamics in a Unitary Bose Gas
Ulrich Eismann, Lev Khaykovich, Sébastien Laurent +8
The low temperature unitary Bose gas is a fundamental paradigm in few-body and many-body physics, attracting wide theoretical and experimental interest. Here we first present a the…
