Two-photon cooling of calcium atoms
Wojciech Adamczyk, Silvan Koch, Claudia Politi +6
We demonstrate sub-Doppler cooling of calcium atoms using a two-photon transition from the ground state to the upper state via the intermediate s…
Observation of vortices in a dipolar supersolid
Eva Casotti, Elena Poli, Lauritz Klaus +6
Supersolids are states of matter that spontaneously break two continuous symmetries: translational invariance due to the appearance of a crystal structure and phase invariance due…
Heating a dipolar quantum fluid into a solid
Juan Sánchez-Baena, Claudia Politi, Fabian Maucher +2
Raising the temperature of a material enhances the thermal motion of particles. Such an increase in thermal energy commonly leads to the melting of a solid into a fluid and eventua…
Observation of vortices and vortex stripes in a dipolar Bose-Einstein condensate
Lauritz Klaus, Thomas Bland, Elena Poli +6
Quantized vortices are the prototypical feature of superfluidity. Pervasive in all natural systems, vortices are yet to be observed in dipolar quantum gases. Here, we exploit the a…
Can angular oscillations probe superfluidity in dipolar supersolids?
Matthew A. Norcia, Elena Poli, Claudia Politi +6
Angular oscillations can provide a useful probe of the superfluid properties of a system. Such measurements have recently been applied to dipolar supersolids, which exhibit both de…
Study of the inter-species interactions in an ultracold dipolar mixture
C. Politi, A. Trautmann, P. Ilzhöfer +4
We experimentally and theoretically investigate the influence of the dipole-dipole interactions (DDIs) on the total inter-species interaction in an erbium-dysprosium mixture. By ro…
Maintaining supersolidity in one and two dimensions
Elena Poli, Thomas Bland, Claudia Politi +5
We theoretically investigate supersolidity in three-dimensional dipolar Bose-Einstein condensates. We focus on the role of trap geometry in determining the dimensionality of the re…
Two-Dimensional Supersolid Formation in Dipolar Condensates
Thomas Bland, Elena Poli, Claudia Politi +5
Dipolar condensates have recently been coaxed to form the long-sought supersolid phase. While one-dimensional supersolids may be prepared by triggering a roton instability, we find…
Two-dimensional supersolidity in a dipolar quantum gas
Matthew A. Norcia, Claudia Politi, Lauritz Klaus +6
Supersolidity -- a quantum-mechanical phenomenon characterized by the presence of both superfluidity and crystalline order -- was initially envisioned in the context of bulk solid…
Birth, life, and death of a dipolar supersolid
Maximilian Sohmen, Claudia Politi, Lauritz Klaus +4
In the short time since the first observation of supersolid states of ultracold dipolar atoms, substantial progress has been made in understanding the zero-temperature phase diagra…
Feshbach Resonances in an Erbium-Dysprosium Dipolar Mixture
Gianmaria Durastante, Claudia Politi, Maximilian Sohmen +4
We report on the observation of heteronuclear magnetic Feshbach resonances in several isotope mixtures of the highly magnetic elements erbium and dysprosium. Among many narrow feat…
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…
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…
