Gluing Methods for Vortex Dynamics in Euler Flows [PDF]
Archive for Rational Mechanics and Analysis, 2018 A classical problem for the two-dimensional Euler flow for an incompressible fluid confined to a smooth domain is that of finding regular solutions with highly concentrated vorticities around N moving vortices .

, 2007 We analyze dynamics of 3D coreless vortices in superfluid films covering porous substrates. The 3D vortex dynamics is derived from the 2D dynamics of the film.

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.

Geometric Characterization of Atmospheric Islands Formed by Two Point Vortices
AxiomsGenerically, in a system with more than three point vortices, there exist regions of stability around each vortex, even if the system is chaotic. These regions are usually called stability islands, and they have a morphology that is hard to characterize.

VORTEX DEVICES OF THE DIESEL AIR SUPPLY SYSTEM: MATHEMATICAL MODEL OF AERODYNAMIC PROCESSES
Вестник СибАДИ, 2020 Introduction. The calculation of effective indicators of the vortex ejector used in the diesel air supply system is a pressing task as it allows significantly reducing time for determination of rational design parameters at the design stage.

Suppression of Kelvon-induced decay of quantized vortices in oblate Bose-Einstein Condensates
, 2011 We study the Kelvin mode excitations on a vortex line in a three-dimensional trapped Bose-Einstein condensate at finite temperature. Our stochastic Gross-Pitaevskii simulations show that the activation of these modes can be suppressed by tightening the ...

Comparative study of vortex dynamics in CaKFe4As4 and Ba0.6K0.4Fe2As2 single crystals. [PDF]
Science Bulletin, 2018 We investigate the vortex dynamics in two typical hole doped iron based superconductors CaKFe4As4 (CaK1144) and Ba0.6K0.4Fe2As2 (BaK122) with similar superconducting transition temperatures.

Numerical investigation of the collision of a vortex ring with a wavy sphere
Vietnam Journal of Science, Technology and EngineeringThe numerical investigation of vortex dynamics resulting from the collision of a vortex ring with a wavy sphere of various wavenumbers (n) at a Reynolds number of 1000 was conducted using a developed remeshed vortex particle method. The influence of the

Fundamental vortices, wall-crossing, and particle-vortex duality
Journal of High Energy Physics, 2017 We explore 1d vortex dynamics of 3d supersymmetric Yang-Mills theories, as inferred from factorization of exact partition functions. Under Seiberg-like dualities, the 3d partition function must remain invariant, yet it is not a priori clear what should ...
