Dynamics of global and local vortices with orientational moduli
Journal of High Energy Physics, 2021 The dynamics of both global and local vortices with non-Abelian orientational moduli is investigated in detail. Head-on collisions of these vortices are numerically simulated for parallel, anti-parallel and orthogonal internal orientations where we find ...

Simplified model for helical vortex dynamics in the wake of an asymmetric rotor
Flow, 2023 Helical vortex systems, such as those found in the wakes of wind turbines, helicopter rotors and propellers, are subject to instabilities that lead to pairing between adjacent vortex loops.

Irreversible flow of vortex matter: polycrystal and amorphous phases [PDF]
, 2009 We investigate the microscopic mechanisms giving rise to plastic depinning and irreversible flow in vortex matter. The topology of the vortex array crucially determines the flow response of this system.

Schrödinger–Chern–Simons vortex dynamics [PDF]
Nonlinearity, 2006 We study the motion of vortices in the planar Ginzburg-Landau model with Schrodinger-Chern-Simons dynamics. We compare the moduli space approximation with the results of numerical simulations of the full field theory and find that there is agreement if the coupling constant is very close to the critical value separating Type I from Type II ...

The Interaction of Two Surface Vortices Near a Topographic Slope in a Stratified Ocean
Fluids, 2017 We study the influence of bottom topography on the interaction of two identical vortices in a two-layer, quasi-geostrophic model. The two vortices have piecewise-uniform potential vorticity and are lying in the upper layer of the model. The topography is

Collisional Dynamics of Half-Quantum Vortices in a Spinor Bose-Einstein Condensate [PDF]
, 2016 We present an experimental study on the interaction and dynamics of half-quantum vortices (HQVs) in an antiferromagnetic spinor Bose-Einstein condensate.

Phase-slips and vortex dynamics in Josephson oscillations between Bose-Einstein condensates [PDF]
, 2014 We study the relation between Josephson dynamics and topological excitations in a dilute Bose-Einstein condensate confined in a double-well trap. We show that the phase slips responsible for the self-trapping regime are created by vortex rings entering ...

Flow Visualisation around Spinning and Non-Spinning Soccer Balls Using the Lattice Boltzmann Method
Proceedings, 2018 The drag and lift of footballs have been mainly measured by wind tunnel tests. In the present study, computational fluid dynamics (CFD) and the lattice Boltzmann method were used to visualise the wakes of spinning and non-spinning footballs and analyse ...
