Mr. Guillaume Gauthier

PhD Student

Guillaume is a postgraduate student at the University of Queensland current undertaking a PhD under the supervision of postdoctoral research fellow Dr. Tyler Neely. His project aim is to progress towards a quantum emulator by controlling and measuring arrays of ultra-cold atoms.

Giant vortex clusters in a two-dimensional quantum fluid
Gauthier Guillaume et al, 2019
Science, 364, 6447, pp. 1264-1267

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 above a certain energy, forming persistent vortex clusters.

Phase and micromotion of Bose-Einstein condensates in a time-averaged ring trap
Bell Thomas A. et al, 2018
Physical Review A, 98, 1

Rapidly scanning magnetic and optical dipole traps have been widely utilized to form time-averaged potentials for ultracold quantum gas experiments.

Configurable microscopic optical potentials for Bose-Einstein condensates using a digital-micromirror device
Gauthier Guillaume et al, 2016
Optica, 10, 3, pp. 1136-1143

The development of novel trapping potentials for degenerate quantum gases has been an important factor driving experimental progress in the field. The introduction of spatial light modulators (SLMs) into quantum gas laboratories means that a range of configurable geometries are now possible.
