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…
Bubble nucleation in a cold spin 1 gas
Thomas P. Billam, Kate Brown, Ian G. Moss
Cold atomic gases offer the prospect of simulating the physics of the very early universe in the laboratory. In the condensate phase, the gas is described by a field theory with ke…
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…
Simulating cosmological supercooling with a cold atom system
Thomas P. Billam, Kate Brown, Ian G. Moss
We perform an analysis of the supercooled state in an analogue to an early universe phase transition based on a one dimensional, two-component Bose gas. We demonstrate that the the…
Transport and current noise characteristics of a T-shape double quantum dot system
K. Brown, M. Crisan, I. Tifrea
We consider the transport and the noise characteristics for the case of a T-shape double quantum dot system using the equation of motion method. Our theoretical results, obtained i…
