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…
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…
Quantum Simulations with Bilayer 2D Bose Gases in Multiple-RF-dressed Potentials
Abel Beregi, Christopher J. Foot, Shinichi Sunami
Multiple-RF (MRF) dressing allows trapping of ultracold atoms in novel spatial geometries, such as highly controllable bilayer structures for 2D ultracold gases, providing unique o…
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…
Probing multiple-frequency atom-photon interactions with ultracold atoms
Kathrin Luksch, Elliot Bentine, Adam J. Barker +4
We dress atoms with multiple-radiofrequency fields and investigate the spectrum of transitions driven by an additional probe field. A complete theoretical description of this rich…
Design of a millimetre-scale magnetic surface trap for cold atoms
Dimitris Trypogeorgos, Stephen D. Albright, Daniel Beesley +1
We study a novel millimetre-scale magnetic trap for ultracold atoms, in which the current carrying conductors can be situated outside the vacuum region, a few mm away from the atom…
Novel techniques to cool and rotate Bose-Einstein condensates in time-averaged adiabatic potentials
M. Gildemeister, B. E. Sherlock, C. J. Foot
We report two novel techniques for cooling and rotating Bose-Einstein condensates in a dilute rubidium vapour that highlight the control and versatility afforded over cold atom sys…
