Physical Review Research, 2019 Vortices are localized planar structures that attain topological stability and can be used to describe collective behavior in a diversity of situations of current interest in nonlinear science. In high energy physics, vortices engender integer winding number and appear under the presence of a local Abelian symmetry.

The Rayleigh–Taylor instability of two-dimensional high-density vortices [PDF]
, 2005 We investigate the stability of variable-density two-dimensional isolated vortices in the frame of incompressible mixing under negligible gravity. The focus on a single vortex flow stands as a first step towards vortex interactions and turbulent mixing ...

Faults Get Colder Through Transient Granular Vortices
Geophysical Research Letters, 2018 Fault temperatures govern their weakening and control the dynamics of earthquakes during slip. Despite predictions of significant temperature rise within fault gouges during earthquake events, observations of frictional melting zones along exhumed faults

Control of Flow around an Oscillating Plate for Lift Enhancement by Plasma Actuators
Applied Sciences, 2019 During insect flight, a feathering motion of the wing’s controls vortex shedding for lift enhancement. In this study, in order to control the flow around a wing flapping with simplified sinusoidal motion, plasma actuators were introduced to ...

Ellipsoidal vortices in rotating stratified fluids : beyond the quasi-geostrophic approximation [PDF]
, 2015 Support for this research has come from the UK Engineering and Physical Sciences Research Council (grant number EP/H001794/1).We examine the basic properties and stability of isolated vortices having uniform potential vorticity (PV) in a non-hydrostatic ...

Physical Review Letters, 2000 Experiments indicating the excitation of whispering gallery type electromagnetic modes by a vortex moving in an annular Josephson junction are reported. At relativistic velocities the Josephson vortex interacts with the modes of the superconducting stripline resonator giving rise to novel resonances on the current-voltage characteristic of the junction.

Acoustic and Thermoacoustic Jet Propulsion [PDF]
Journal of Applied Fluid Mechanics, 2023 This manuscript bridges the fields of jet propulsion, synthetic jets and thermoacoustic engines. We introduce the case that synthetic jets in air can be considered a consistent approach for propulsion systems. To date, studies on synthetic jet propulsion

Physical Review D, 1998 We present a discussion of embedded vortices in general Yang-Mills theories. The origin of a family structure of solutions is shown to be group theoretic in nature and a procedure for its determination is developed. Vortex stability can be quantified into three types: Abelian topological stability, non-Abelian topological stability, and dynamical ...

Quasi-geostrophic vortices in compressible atmospheres [PDF]
, 2005 This paper considers the effect of an exponential variation in the background density field (as exists in compressible atmospheres) on the structure and dynamics of the quasi-geostrophic system, and compares the results with the corresponding Boussinesq ...

Vortices and Polynomials [PDF]
Studies in Applied Mathematics, 2009 The relationship between point vortex dynamics and the properties of polynomials with roots at the vortex positions is discussed. Classical polynomials, such as the Hermite polynomials, have roots that describe the equilibria of identical vortices on the line. Stationary and uniformly translating vortex configurations with vortices of the same strength
