Universal coarsening of a two-dimensional Bose gas under conservative evolution
Andrew J. Groszek, Thomas P. Billam
We investigate the phase ordering dynamics of a uniform two-dimensional Bose gas quenched to a finite temperature in the superfluid phase. Starting from a defect-rich, far-from-equ…
Axially confined binary quantum droplets: ground states and central vortices
Srivatsa B. Prasad, Thomas P. Billam, Nick G. Parker
Ultracold miscible mixtures of bosonic gases have been observed to form quantum droplet states stabilized by beyond-mean-field quantum fluctuations. Here we study the properties of…
Mitigating boundary effects in finite temperature simulations of false vacuum decay
Kate Brown, Ian G. Moss, Thomas P. Billam
The physics of false vacuum decay during first-order phase transitions in the early universe may be studied in the laboratory via cold-atom analogue simulators. However, a key diff…
Generalized cold-atom simulators for vacuum decay
Alexander C. Jenkins, Ian G. Moss, Thomas P. Billam +3
Cold-atom analog experiments are a promising new tool for studying relativistic vacuum decay, enabling one to empirically probe early-Universe theories in the laboratory. However,…
Trapped Imbalanced Quantum Droplets
Thomas A. Flynn, Nick A. Keepfer, Nick G. Parker +1
A two-component quantum droplet is an attractive mixture of ultracold bosons stabilised against collapse by quantum fluctuations. Commonly, two-component quantum droplets are studi…
Observation of false vacuum decay via bubble formation in ferromagnetic superfluids
Alessandro Zenesini, Anna Berti, Riccardo Cominotti +7
In quantum field theory, the decay of an extended metastable state into the real ground state is known as ``false vacuum decay'' and it takes place via the nucleation of spatially…
