Critical Velocity and Arrest of a Superfluid in a Point-Like Disordered Potential
R. Doran, A. J. Groszek, T. P. Billam
Superfluid flow past a potential barrier is a well studied problem in ultracold Bose gases, however, fewer studies have considered the case of flow through a disordered potential.…
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…
Geometric phases of a vortex in a superfluid
Rodney E. S. Polkinghorne, Andrew J. Groszek, Tapio P. Simula
We consider geometric phases of mobile quantum vortices in superfluid Bose-Einstein condensates. Haldane and Wu [Phys. Rev. Lett. 55, 2887 (1985)] showed that the geometric phase,…
Crossover in the dynamical critical exponent of a quenched two-dimensional Bose gas
Andrew J. Groszek, Paolo Comaron, Nikolaos P. Proukakis +1
We study the phase ordering dynamics of a uniform Bose gas in two dimensions following a quench into the ordered phase. We explore the crossover between dissipative and conservativ…
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…
Decaying quantum turbulence in a two-dimensional Bose-Einstein condensate at finite temperature
Andrew J. Groszek, Matthew J. Davis, Tapio P. Simula
We numerically model decaying quantum turbulence in two-dimensional disk-shaped Bose-Einstein condensates, and investigate the effects of finite temperature on the turbulent dynami…
