Fraunhofer Patterns in Atomic Josephson Junctions
Kevin T. Geier, Giampiero Marchegiani, Vijay Pal Singh +2
Driven atomic Josephson junctions allow one to monitor phase-coherent dynamics with unprecedented control and flexibility of the system's physical conditions. While cold-atom manif…
Coupling-induced universal dynamics in bilayer two-dimensional Bose gases
En Chang, Vijay Pal Singh, Abel Beregi +4
The emergence of order in many-body systems and the associated self-similar dynamics governed by dynamical scaling laws is a hallmark of universality far from equilibrium. Measurin…
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…
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…
Detecting Phase Coherence of 2D Bose Gases via Noise Correlations
Shinichi Sunami, Vijay P. Singh, Erik Rydow +4
We measure the noise correlations of two-dimensional (2D) Bose gases after free expansion, and use them to characterize the in-situ phase coherence across the Berezinskii-Kosterlit…
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…
