Breathing Mode of a BEC Repulsively Interacting with a Fermionic Reservoir
Bo Huang, Isabella Fritsche, Rianne S. Lous +4
We investigate the fundamental breathing mode of a small-sized elongated Bose-Einstein condensate coupled to a large Fermi sea of atoms. Our observations show a dramatic shift of t…
Production of a degenerate Fermi-Fermi mixture of dysprosium and potassium atoms
Cornelis Ravensbergen, Vincent Corre, Elisa Soave +3
We report on the realization of a mixture of fermionic Dy and fermionic K where both species are deep in the quantum-degenerate regime. Both components are spin-pola…
Probing the Interface of a Phase-Separated State in a Repulsive Bose-Fermi Mixture
Rianne S. Lous, Isabella Fritsche, Michael Jag +4
We probe the interface between a phase-separated Bose-Fermi mixture consisting of a small BEC of K residing in a large Fermi sea of Li. We quantify the residual spatial…
Accurate Determination of the Dynamical Polarizability of Dysprosium
C. Ravensbergen, V. Corre, E. Soave +4
We report a measurement of the dynamical polarizability of dysprosium atoms in their electronic ground state at the optical wavelength of 1064 nm, which is of particular interest f…
