Efficient simulation of Bose-Einstein condensates in nontrivial topologies
Abel Beregi, Jean-Baptiste Gerent, Nathan Lundblad
Bubble-shaped Bose-Einstein condensates (BECs) constitute a unique class of quantum fluids with a hollow, thin-shell geometry that supports a wide variety of phenomena that are dis…
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…
Universal Scaling of the Dynamic BKT Transition in Quenched 2D Bose Gases
Shinichi Sunami, Vijay P. Singh, David Garrick +6
While renormalization group theory is a fully established method to capture equilibrium phase transitions, the applicability of RG theory to universal non-equilibrium behavior rema…
Cavity optomechanics in a fiber cavity: the role of stimulated Brillouin scattering
Abel Beregi, Peter F. Barker, Antonio Pontin
We study the role of stimulated Brillouin scattering in a fiber cavity by numerical simulations and a simple theoretical model and find good agreement between experiment, simulatio…
Observation of the BKT Transition in a 2D Bose Gas via Matter-Wave Interferometry
Shinichi Sunami, Vijay P. Singh, David Garrick +6
We probe local phase fluctuations of trapped two-dimensional (2D) Bose gases using matter-wave interferometry. This enables us to measure the phase correlation function, which chan…
Coherent splitting of two-dimensional Bose gases in magnetic potentials
Adam J. Barker, Shinichi Sunami, David Garrick +4
Investigating out-of-equilibrium dynamics with two-dimensional (2D) systems is of widespread theoretical interest, as these systems are strongly influenced by fluctuations and ther…
Realising a species-selective double well with multiple-radiofrequency-dressed potentials
A. J. Barker, S. Sunami, D. Garrick +4
Techniques to manipulate the individual constituents of an ultracold mixture are key to investigating impurity physics. In this work, we confine a mixture of the hyperfine ground s…
