Anomalous non-thermal fixed point in a quasi-two-dimensional dipolar Bose gas
Niklas Rasch, Lauriane Chomaz, Thomas Gasenzer
The emergence of distinctly sub-diffusive scaling in the vicinity of an anomalous non-thermal fixed point is discussed in a quasi-two-dimensional dipolar Bose gas in the superfluid…
Kibble-Zurek scaling of the superfluid-supersolid transition in an elongated dipolar gas
Wyatt Kirkby, Hayder Salman, Thomas Gasenzer +1
We simulate interaction quenches crossing from a superfluid to a supersolid state in a dipolar quantum gas of atoms, trapped in an elongated tube with periodi…
Quantum-stabilized states in magnetic dipolar quantum gases
Lauriane Chomaz
A decade ago, a universal stabilization mechanism driven by quantum fluctuations was discovered in ultracold Bose gases of highly magnetic atoms. This mechanism prevents these syst…
Ab initio Complex Langevin computation of the roton gap for a dipolar Bose condensate
Philipp Heinen, Wyatt Kirkby, Lauriane Chomaz +1
We compute from first principles the dispersion relation of a dipolar Bose gas of erbium atoms close to the roton instability by employing the Complex Langevin (CL) algorit…
An experimental platform for studying the heteronuclear Efimov effect with an ultracold mixture of Li and Cs atoms
Eleonora Lippi, Manuel Gerken, Stephan Häfner +10
We present the experimental apparatus enabling the observation of the heteronuclear Efimov effect in an optically trapped ultracold mixture of Li-Cs with high-resolutio…
Effect of trap imperfections on the density of a quasi-two-dimensional uniform dipolar quantum Bose gas
Thibault Bourgeois, Lauriane Chomaz
We theoretically investigate the impact of weak static perturbations of a flat potential on the density of a quasi-two-dimensional dipolar Bose gas. {We consider the perturbative e…
