Universal non-Gaussian order parameter statistics in 2D superfluids
Abel Beregi, En Chang, Erik Rydow +2
Fluctuations are an intrinsic feature of many-body systems, and their full statistical distributions reveal a wealth of information about the underlying physics. Of particular inte…
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…
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…
CNN-Based Vortex Detection in Atomic 2D Bose Gases in the Presence of a Phononic Background
Magnus Sesodia, Shinichi Sunami, En Chang +3
Quantum vortices play a crucial role in both equilibrium and dynamical phenomena in two-dimensional (2D) superfluid systems. Experimental detection of these excitations in 2D ultra…
