Bloch Oscillations

Bloch Oscillations

We study Bloch oscillations of an erbium quantum droplet  

3D array of large-spin fermions

3D array of large-spin fermions

In joint theoretical and experimental work with our theory colleagues A.-M. Rey (JILA) and B. Zhu (ITAMP) we investigate dipolar induced magnetization-conserving spin exchange dynamics with fermionic Er in a 3D optical lattice

Excitation spectrum of a trapped dipolar supersolid

Excitation spectrum of a trapped dipolar supersolid

In a combined theory and experimental work, we study the elementary excitations of trapped dipolar quantum gases crossing from regular superfluid to supersolid.

Observation of roton quasiparticles in Erbium

Observation of roton quasiparticles in Erbium

In collaboration with our theory collaborators from Innsbruck and Hannover, we have observed for the first time so-called roton quasiparticles in an ultracold bosonic gas of erbium atoms.

Polarizability of Erbium

Polarizability of Erbium

In collaboration with our theory colleagues from Paris, we have determined the dynamical polarizability of ultracold erbium atoms.

Crossover from a BEC to a macrodroplet

Crossover from a BEC to a macrodroplet

Together with our theory colleagues from Hannover, we have investigated the formation of a macrodroplet state in an ultracold bosonic gas of erbium atoms.

Extended Bose-Hubbard Model

Extended Bose-Hubbard Model

We have studied the extended Bose-Hubbard Model with dipolar Er atoms as well as how the superfluid-to-Mott-insulator transition is modified by the dipole-dipole interaction.

Quantum Chaos in Ultracold Collisions of Erbium

Quantum Chaos in Ultracold Collisions of Erbium

We have studied the scattering behavior of ultracold Er atoms and observed an enormous number of Fano-Feshbach scattering resonances.

ERBIUM LAB

Dipolar Quantum Gases of Erbium Atoms 

Erbium has very special properties that make it unique: a very strong magnetic moment, many valence electrons, clock transitions, and an extremely rich internal atomic structure.

In the ERBIUM LAB we bring all these properties in the quantum regime together to study strongly dipolar gases both in the continuum and in optical lattices.  Recently, the ERBIUM team has observed roton excitations, the counterintuitive and long-sought supersolid states, deformed Fermi surface, Bose-Hubbard systems with long-range interaction, spin manipulation via the clock transition, and much more!
