In-plane field-induced vortex liquid correlations in underdoped Bi_2Sr_2CaCu_2O_8+\delta [PDF]

open access: yes, 2007
The effect of a magnetic field component parallel to the superconducting layers on longitudinal Josephson plasma oscillations in the layered high temperature superconductor Bi$_2$Sr$_2$CaCu$_2$O$_{8+\delta}$ is shown to depend on the thermodynamic state ...

Field tunable three-dimensional magnetic nanotextures in cobalt-nickel nanowires

open access: yesPhysical Review Research, 2021
Cylindrical magnetic nanowires with large transversal magnetocrystalline anisotropy have been shown to sustain nontrivial magnetic configurations resulting from the interplay of spatial confinement, exchange, and anisotropies.

Interaction of a shock with a longitudinal vortex [PDF]

open access: yesJournal of Fluid Mechanics, 1997
In this paper we study the interaction of a shock with an axisymmetric longitudinal vortex. A linearized analysis for small vortex strength is performed, and compared with results from a high-order axisymmetric shock-fitted Euler solution. It is confirmed that for weak vortices, predictions from linear theory agree well with results from ...

THE INFLUENCE OF FEATURES OF VORTEX FLOW ON AERODYNAMIC CHARACTERISTICS OF THE SUPERSONIC MANEUVERABLE AIRCRAFT MODEL

open access: yesНаучный вестник МГТУ ГА, 2019
The paper presents the influence of the vortex flow features, in particular, the phenomenon of vortex burst on the longitudinal and lateral aerodynamic characteristics of the maneuverable aircraft model with a sharp-edged fore-body.

Influence of Cross-Sectional Configuration on the Longitudinal Vortex Excitation of the Upstream Cylinder in Cruciform Two-Cylinder System

open access: yesJournal of Fluid Science and Technology, 2006
In earlier works by the present authors, it was shown that a large cross-flow excitation is induced to a circular cylinder by setting another cylinder downstream in a cruciform arrangement with a certain gap between them, caused by longitudinal vortices ...

Enhancement of Optical Spin-Orbit Coupling in Anisotropic ENZ Metamaterials

open access: yesIEEE Photonics Journal, 2023
Vector vortex beams which possess complex intensity and polarisation patterns, and phase or polarisation singularities are important in a variety of applications ranging from high resolution imaging and data transmission to nonlinear optics and quantum ...

On velocity structure functions and the spherical vortex model for isotropic turbulence [PDF]

open access: yes, 2001
We investigate a stochastic model for homogeneous, isotropic turbulence based on Hill's spherical vortex. This is an extension of the method of Synge and Lin [Trans. R. Soc. Can.

Experimental Investigation of the Generation of a Longitudinal Vortex in a Transverse Synthetic Jet with Different Excitation Frequencies

open access: yesJournal of Fluid Science and Technology, 2011
In this paper, experimental study was undertaken to investigate the effect of excitation frequency of a synthetic jet on the generation of a longitudinal vortex produced by the interaction between a jet and a crossflow in a wind tunnel.

Transverse depinning in strongly driven vortex lattices with disorder

open access: yes, 1999
Using numerical simulations we investigate the transverse depinning of moving vortex lattices interacting with random disorder. We observe a finite transverse depinning barrier for vortex lattices that are driven with high longitudinal drives, when the ...
