A high-speed, large-aperture 3D printed laser shutter for cold atom experiments
Samantha L. Rubinstein, Charles W. Woffinden, Maarten T. M. Christenhusz +2
Cold atom experiments require optical shutters with rapid and repeatable actuation. Existing solutions often involve high cost, limited aperture diameter and slow transitioning. We…
Shear-Induced Decaying Turbulence in Bose-Einstein Condensates
Simeon Simjanovski, Guillaume Gauthier, Halina Rubinsztein-Dunlop +2
We study the creation and breakdown of a quantized vortex shear layer forming between a stationary Bose-Einstein condensate and a stirred-in persistent current. Once turbulence is…
Melting of a vortex matter Wigner crystal
Tyler W. Neely, Guillaume Gauthier, Charles Glasspool +2
The two-dimensional One-Component Plasma (OCP) is a foundational model of the statistical mechanics of interacting particles, describing phenomena common to astrophysics, turbulenc…
Optimizing persistent currents in a ring-shaped Bose-Einstein condensate using machine learning
Simeon Simjanovski, Guillaume Gauthier, Matthew J. Davis +2
We demonstrate a method for generating persistent currents in Bose-Einstein condensates by using a Gaussian process learner to experimentally control the stirring of the superfluid…
Viability of rotation sensing using phonon interferometry in Bose-Einstein condensates
Charles W. Woffinden, Andrew J. Groszek, Guillaume Gauthier +7
We demonstrate the use of a ring-shaped Bose-Einstein condensate as a rotation sensor by measuring the interference between two counter-propagating phonon modes imprinted azimuthal…
Dynamic high-resolution optical trapping of ultracold atoms
Guillaume Gauthier, Thomas A. Bell, Alexander B. Stilgoe +3
All light has structure, but only recently it has become possible to construct highly controllable and precise potentials so that most laboratories can harness light for their spec…
Turbulent relaxation to equilibrium in a two-dimensional quantum vortex gas
Matthew T. Reeves, Kwan Goddard-Lee, Guillaume Gauthier +9
We experimentally study emergence of microcanonical equilibrium states in the turbulent relaxation dynamics of a two-dimensional chiral vortex gas. Same-sign vortices are injected…
Roadmap on Atomtronics: State of the art and perspective
L. Amico, M. Boshier, G. Birkl +56
Atomtronics deals with matter-wave circuits of ultra-cold atoms manipulated through magnetic or laser-generated guides with different shapes and intensities. In this way, new types…
Quantitative acoustic models for superfluid circuits
Guillaume Gauthier, Stuart S. Szigeti, Matthew T. Reeves +5
We experimentally realize a highly tunable superfluid oscillator circuit in a quantum gas of ultracold atoms and develop and verify a simple lumped-element description of this circ…
Phase and micromotion of Bose-Einstein condensates in a time-averaged ring trap
Thomas A. Bell, Guillaume Gauthier, Tyler W. Neely +3
Rapidly scanning magnetic and optical dipole traps have been widely utilised to form time-averaged potentials for ultracold quantum gas experiments. Here we theoretically and exper…
Giant Vortex Clusters in a Two-Dimensional Quantum Fluid
Guillaume Gauthier, Matthew T. Reeves, Xiaoquan Yu +6
Adding energy to a system through transient stirring usually leads to more disorder. In contrast, point-like vortices in a bounded two-dimensional fluid are predicted to reorder ab…
Direct imaging of a digital-micromirror device for configurable microscopic optical potentials
G. Gauthier, I. Lenton, N. McKay Parry +4
Programable spatial light modulators (SLMs) have significantly advanced the configurable optical trapping of particles. Typically, these devices are utilized in the Fourier plane o…
