Reconnection of superfluid vortex bundles
Sultan Z. Alamri, Anthony J. Youd, Carlo F. Barenghi
Using the vortex filament model and the Gross Pitaevskii nonlinear Schroedinger equation, we show that bundles of quantised vortex lines in helium II are structurally robust and ca…
Finite temperature vortex dynamics in Bose Einstein condensates
B. Jackson, N. P. Proukakis, C. F. Barenghi +1
We study the decay of vortices in Bose-Einstein condensates at finite temperatures by means of the Zaremba Nikuni Griffin formalism, in which the condensate is modelled by a Gross…
Ballistic propagation of thermal excitations near a vortex in superfluid He3-B
C. F. Barenghi, Y. A. Sergeev, N. Suramlishvili
Andreev scattering of thermal excitations is a powerful tool for studying quantized vortices and turbulence in superfluid He3-B at very low temperatures. We write Hamilton's equati…
Disordered vortex arrays in a two-dimensional condensate
E. J. M. Madarassy, C. F. Barenghi
We suggest a method to create turbulence in a Bose-Einstein condensate. The method consists in, firstly, creating an ordered vortex array, and, secondly, imprinting a phase differe…
Vortex dynamics in trapped Bose-Einstein condensate
E. J. M. Madarassy, C. F. Barenghi
We perform numerical simulations of vortex motion in a trapped Bose-Einstein condensate by solving the two-dimensional Gross-Pitaevskii Equation in the presence of a simple phenome…
Stretching in a model of a turbulent flow
Andrew W. Baggaley, Carlo F. Barenghi, Anvar Shukurov
Using a multi-scaled, chaotic flow known as the KS model of turbulence, we investigate the dependence of Lyapunov exponents on various characteristics of the flow. We show that the…
