Quantum undular bores, rainbows, and event horizons in superfluid dam breaks
Liam M. Farrell, Wyatt Kirkby, Alex Harris +3
The sudden removal of a potential barrier from a Bose-Einstein condensate (BEC) gives rise to a quantum version of a hydrodynamic dam break and leads to rich wave dynamics that hav…
Competing triangular and stripe supersolid orders in a dipolar quantum gas
Karthik Chandrashekara, Christian Gölzhäuser, Lily Platt +6
Supersolids are exotic quantum states in which long-range phase coherence coexists, and may interplay, with emergent spatial orders. A particularly rich phase diagram featuring sev…
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…
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…
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) algorith…
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…
Excitations of a binary dipolar supersolid
W. Kirkby, Au-Chen Lee, D. Baillie +4
We predict a rich excitation spectrum of a binary dipolar supersolid in a linear crystal geometry, where the ground state consists of two partially immiscible components with alter…
