Measurement of the excitation spectrum of a dipolar gas in the macrodroplet regime
J. J. A. Houwman, D. Baillie, P. B. Blakie +3
The excitation spectrum of a cigar-shaped strongly dipolar quantum gas at the crossover from a Bose-Einstein condensate to a trapped macrodroplet is predicted to exhibit peculiar f…
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…
Phase coherence in out-of-equilibrium supersolid states of ultracold dipolar atoms
Philipp Ilzhöfer, Maximilian Sohmen, Gianmaria Durastante +7
A supersolid is a fascinating phase of matter, combining the global phase coherence of a superfluid with hallmarks of solids, e.g. a spontaneous breaking of the translational symme…
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…
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…
