Observation of Atom Number Fluctuations in a Bose-Einstein Condensate

M. A. Kristensen, M. B. Christensen, M. Gajdacz +7

Fluctuations are a key property of both classical and quantum systems. While the fluctuations are well understood for many quantum systems at zero temperature, the case of an inter…

Density-wave steady-state phase of dissipative ultracold fermions with nearest-neighbor interactions

Jaromir Panas, Michael Pasek, Arya Dhar +6

In this work we investigate the effect of local dissipation on the presence of density-wave ordering in spinful fermions with both local and nearest-neighbor interactions as descri…

Observation of a dipolar quantum gas with metastable supersolid properties

Luca Tanzi, Eleonora Lucioni, Francesca Famà +6

The competition of dipole-dipole and contact interactions leads to exciting new physics in dipolar gases, well-illustrated by the recent observation of quantum droplets and rotons…

Excitations of a vortex line in an elongated dipolar condensate

Au-Chen Lee, D. Baillie, R. N. Bisset +1

We characterise the properties of a vortex line in an elongated dipolar Bose-Einstein condensate. Increasing the strength of the dipole-dipole interactions (DDIs) relative to the s…

Tailored single-atom collisions at ultra-low energies

Felix Schmidt, Daniel Mayer, Quentin Bouton +5

We employ collisions of individual atomic cesium (Cs) impurities with an ultracold rubidium (Rb) gas to probe atomic interaction with hyperfine- and Zeeman-state sensitivity. Contr…

Dimensional crossover for the beyond-mean-field correction in Bose gases

Tobias Ilg, Jan Kumlin, Luis Santos +2

We present a detailed beyond-mean-field analysis of a weakly interacting Bose gas in the crossover from three to low dimensions. We find an analytical solution for the energy and p…
