Accurate determination of the scattering length of erbium atoms
A. Patscheider, L. Chomaz, G. Natale +7
An accurate knowledge of the scattering length is fundamental in ultracold quantum gas experiments and essential for the characterisation of the system as well as for a meaningful…
High-energy Bragg scattering measurements of a dipolar supersolid
D. Petter, A. Patscheider, G. Natale +9
We present an experimental and theoretical study of the high-energy excitation spectra of a dipolar supersolid. Using Bragg spectroscopy, we study the scattering response of the sy…
Excitation spectrum of a trapped dipolar supersolid and its experimental evidence
G. Natale, R. M. W. van Bijnen, A. Patscheider +4
We study the spectrum of elementary excitations of a dipolar Bose gas in a three-dimensional anisotropic trap across the superfluid-supersolid phase transition. Theoretically, we s…
Controlling Dipolar Exchange Interactions in a Dense 3D Array of Large Spin Fermions
A. Patscheider, B. Zhu, L. Chomaz +5
Dipolar interactions are ubiquitous in nature and rule the behavior of a broad range of systems spanning from energy transfer in biological systems to quantum magnetism. Here, we s…
Long-lived and transient supersolid behaviors in dipolar quantum gases
L. Chomaz, D. Petter, P. Ilzhöfer +9
By combining theory and experiments, we demonstrate that dipolar quantum gases of both Er and Dy support a state with supersolid properties, where a spontaneous den…
Probing the roton excitation spectrum of a stable dipolar Bose gas
D. Petter, G. Natale, R. M. W. van Bijnen +4
We measure the excitation spectrum of a stable dipolar Bose--Einstein condensate over a wide momentum-range via Bragg spectroscopy. We precisely control the relative strength, $ε_{…
Realization of a Strongly Interacting Fermi Gas of Dipolar Atoms
S. Baier, D. Petter, J. H. Becher +5
We realize a two-component dipolar Fermi gas with tunable interactions, using erbium atoms. Employing a lattice-protection technique, we selectively prepare deeply degenerate mixtu…
Quantum-fluctuation-driven crossover from a dilute Bose-Einstein condensate to a macro-droplet in a dipolar quantum fluid
L. Chomaz, S. Baier, D. Petter +4
In a joint experimental and theoretical effort, we report on the formation of a macro-droplet state in an ultracold bosonic gas of erbium atoms with strong dipolar interactions. By…
Extended Bose-Hubbard Models with Ultracold Magnetic Atoms
S. Baier, M. J. Mark, D. Petter +6
The Hubbard model underlies our understanding of strongly correlated materials. While its standard form only comprises interaction between particles at the same lattice site, its e…
