Josephson Dynamics in 2D Ring-shaped Condensates
Koon Siang Gan, Vijay Pal Singh, Luigi Amico +1
We investigate Josephson transport in a fully closed, two-dimensional superfluid circuit formed by a ring-shaped 87Rb Bose-Einstein condensate that contains two optical barriers ac…
Realizing an Atomtronic AQUID in a Rotating-Box Potential
Kaspar Görg, Ludwig Mathey, Vijay Pal Singh
Atomtronic devices are matter-wave circuits designed to emulate the functional behavior of their electronic counterparts. Motivated by superconducting quantum interference devices…
Atomic Josephson Parametric Amplifier
Vijay Pal Singh, Luigi Amico, Ludwig Mathey
We study the dynamics of a driven atomic Josephson junction that we propose as a parametric amplifier. By periodically modulating the position of the barrier, we induce a small cur…
Designing Atomtronic Circuits via Superfluid Dynamics
Sarah Jährling, Vijay Pal Singh, Ludwig Mathey
We propose to design atomtronic circuits with Bose-Einstein condensates (BECs) in circuit-like traps that are controlled via mobile barriers. Using classical-field simulations, we…
Static impurity in a mesoscopic system of SU() fermionic matter-waves
Juan Polo, Wayne J. Chetcuti, Anna Minguzzi +2
We investigate the effects of a static impurity, modeled by a localized barrier, in a one-dimensional mesoscopic system comprised of strongly correlated repulsive SU()-symmetric…
Observation of a Bilayer Superfluid with Interlayer Coherence
Erik Rydow, Vijay P. Singh, Abel Beregi +4
Controlling the coupling between different degrees of freedom in many-body systems is a powerful technique for engineering novel phases of matter. We create a bilayer system of two…
