Vortex Polarization States in Nanoscale Ferroelectric Arrays

Nano Letters, 2009
Two-dimensional arrays of ferroelectric lead zirconate titanate (PZT) nanodots were fabricated using pulsed laser deposition through ultrathin anodic aluminum oxide membrane stencil masks. The static distribution of polarization configurations was investigated using in- and out-of-plane piezoresponse force microscopy (PFM).

Dynamics of a polarized vortex ring

Journal of Fluid Mechanics, 1994
This paper builds on our claim that most vortical structures in transitional and turbulent flows are partially polarized. Polarization is inferred by the application of helical wave decomposition. We analyse initially polarized isolated viscous vortex rings through direct numerical simulation of the Navier-Stokes equations using divergence-free ...

Polarization control in magnonic vortex crystals

2015 IEEE Magnetics Conference (INTERMAG), 2015
Wave transmission media created by a periodically modulated magnetic material are referred to as magnonic crystals [1]. The dynamics of magnonic crystals are described by common concepts of solid state physics, i.e., group velocity, density of states, and band structure.

Tropical Impacts From Polar Vortex Events

Stratospheric sudden warmings and other polar vortex events have well-documented impacts on winter surface weather and climate over middle to high latitudes. However, the scientific understanding of the influence of the polar stratosphere on the tropics remains in its early stages. There are two primary pathways through which these influences can occur.
