Controlled generation of 3D vortices in driven atomic Josephson junctions
Vijay Pal Singh, Ludwig Mathey, Herwig Ott +1
We propose an ac-driven atomic Josephson junction as a clean and tunable source of three dimensional (3D) solitary waves in quantum fluids. Depending on the height of the junction…
Weak-link to tunneling crossover in an atomic Josephson junction
Vijay Pal Singh, Erik Bernhart, Marvin Röhrle +3
We present a unified, quantitative description of transport across the crossover between hydrodynamic weak-link flow and tunneling-dominated Josephson dynamics in a three-dimension…
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…
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…
