Why free markets die: An evolutionary perspective
Eduardo Viegas, Stuart P. Cockburn, Henrik Jeldtoft Jensen +1
Company mergers and acquisitions are often perceived to act as catalysts for corporate growth in free markets systems: it is conventional wisdom that those activities lead to bette…
The Stochastic Gross-Pitaevskii Methodology
Stuart P. Cockburn, Nick P. Proukakis
We review the stochastic Gross-Pitaevskii approach for non-equilibrium finite temperature Bose gases, focussing on the formulation of Stoof; this method provides a unified descript…
Phase coherence in quasicondensate experiments: an ab initio analysis via the stochastic Gross-Pitaevskii equation
D. Gallucci, S. P. Cockburn, N. P. Proukakis
We perform an ab initio analysis of the temperature dependence of the phase coherence length of finite temperature, quasi-one-dimensional Bose gases measured in the experiments of…
Fluctuating and dissipative dynamics of dark solitons in quasi-condensates
S. P. Cockburn, H. E. Nistazakis, T. P. Horikis +3
The fluctuating and dissipative dynamics of matter-wave dark solitons within harmonically trapped, partially condensed Bose gases is studied both numerically and analytically. A st…
A comparison between microscopic methods for finite temperature Bose gases
S. P. Cockburn, A. Negretti, N. P. Proukakis +1
We analyze the equilibrium properties of a weakly interacting, trapped quasi-one-dimensional Bose gas at finite temperatures and compare different theoretical approaches. We focus…
Matter-wave dark solitons: stochastic vs. analytical results
S. P. Cockburn, H. E. Nistazakis, T. P. Horikis +3
The dynamics of dark matter-wave solitons in elongated atomic condensates are discussed at finite temperatures. Simulations with the stochastic Gross-Pitaevskii equation reveal a n…
