Probing universality of 2D quantum systems with bilayer Bose gases by Beregi, A

“…The creation of a degenerate quantum gas is demonstrated, with evaporative cooling performed entirely in RF-dressed potential. …”

Topics in quantum measurement of many-body systems by Elliott, T

“…After deriving a general result, we consider the specific case of impurity atoms immersed in a quantum gas, and demonstrate that this enables density-related properties of the gas to be inferred from measurements of solely the impurity internal state. …”

Towards an imaging lattice for magnetically trapped atoms by Owen, E

“…</p> <p>An introduction to the specific challenge of performing a quantum simulation of the fractional quantum Hall effect is given, with the link to and nature of the imaging lattice technique explained. The existing quantum-gas machine that has been developed to produce Bose-Einstein condensates of ⁸⁷Rb in this work is then described, including the new optical lattice subsystem and the associated diode laser system. …”

Bose gases in double-well potentials by Barker, AJ

“…</p> <p>Furthermore, we describe the application of machine learning methods to optimise the experimental sequence, in particular the stages of laser cooling and evaporative cooling which are necessary to achieve a quantum gas. We compare several machine learning methods, including Artificial Neural Networks and Gaussian Process regression, and determine experimental parameters which have the strongest influence on the desired outcome. …”

Gauge matters: observing the vortex-nucleation transition in a Bose condensate by L J LeBlanc, K Jiménez-García, R A Williams, M C Beeler, W D Phillips, I B Spielman

“…Measurements of this kind offer opportunities for studying phase in less-well-understood quantum gas systems.…”

Dynamical phase diagram of ultracold Josephson junctions by K Xhani, L Galantucci, C F Barenghi, G Roati, A Trombettoni, N P Proukakis

“…We provide a complete study of the phase diagram characterising the distinct dynamical regimes emerging in a three-dimensional Josephson junction in an ultracold quantum gas. Considering trapped ultracold superfluids separated into two reservoirs by a barrier of variable height and width, we analyse the population imbalance dynamics following a variable initial population mismatch. …”
