A Maxwell Fish-Eye Lens in a Bose-Einstein Condensate
Jelte Duchêne, Elinor Kath, Floriane Arrouas +7
We experimentally realize an analogue of the optical Maxwell fish-eye lens (MFEL) using phononic excitations in a Bose-Einstein condensate (BEC). A MFEL is characterized by a radia…
Quantum vortex channels as Josephson junctions
Natalia Masalaeva, Wyatt Kirkby, Francesca Ferlaino +1
In quantum gases, weak links are typically realized with externally imposed optical potentials. We show that, in rotating binary condensates, quantized vortices in one component fo…
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…
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…
