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…

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…
