False vacuum decay in an ultracold spin-1 Bose gas
Thomas P. Billam, Kate Brown, Ian G. Moss
We propose an ultracold atom analogue of early universe vacuum decay using all three states of a spin-1 Bose gas. We consider a one-dimensional system with both radio frequency and…
Simulating cosmological supercooling with a cold atom system II
Thomas P. Billam, Kate Brown, Andrew J. Groszek +1
We perform an analysis of the supercooled state in an analogue of an early universe phase transition based on a one dimensional, two-component Bose gas with time-dependent interact…
Soliton interferometry with very narrow barriers obtained from spatially dependent dressed states
Callum L. Grimshaw, Thomas P. Billam, Simon A. Gardiner
Bright solitons in atomic Bose--Einstein condensates are strong candidates for high precision matter-wave interferometry, as their inherent stability against dispersion supports lo…
