Emergence of chaotic scattering in ultracold Er and Dy
ERBIUM NEWS:
Now in PRX! We show that for ultracold magnetic lanthanide atoms (Er and Dy) chaotic scattering emerges due to a combination of anisotropic interaction potentials and Zeeman coupling under an external magnetic field. The scattering is studied in a collaborative experimental and theoretical effort, involving our group, the Stuttgart Dy Group led by T. Pfau and the theory colleagues S. Kotochigova and E. Tiesinga in the USA. [more]
Ultracold polar molecules composed of strongly magnetic atoms
ERBIUM NEWS
Now in PRL! We created a novel type of dipolar system made of two ultracold bosonic dipolar atoms bounded into a molecules. This work is the result of a combined experimental and theoretical effort between our group, the cold collisions group at LAC in France, and the theory group at Temple University (USA). [more]
Observation of Fermi surface deformation in a dipolar quantum gas
ERBIUM NEWS
Now in Science! In the presence of isotropic interactions, the Fermi surface of an ultracold Fermi gas is spherical. Introducing anisotropic interactions can deform it. This effect is subtle and challenging to observe experimentally. We report the observation of such a Fermi surface deformation in a degenerate dipolar Fermi gas of erbium atoms. The deformation is caused by the interplay between strong magnetic dipole-dipole interaction and the Pauli exclusion principle. We demonstrate the many-body nature of the effect and its tunability with the Fermi energy. Our observation provides a basis for future studies on anisotropic many-body phenomena in normal and superfluid phases. [more]
Quantum Chaos in Ultracold Collisions of Erbium
ERBIUM NEWS
We have studied the scattering behavior of ultracold Er atoms and observed an enormous number of Fano-Feshbach scattering resonances and demonstrate high correlation in the spectra, underlying chaotic scattering between the particles. This work, now published in NATURE, is a joint effort between our group, John L. Bohn from JILA (Boulder, Colorado), and the team of Svetlana Kotochigova at Temple University (USA). Nice media coverage (in italian) from the MEDIA INAF. [more]
