Background: The spectral polarization state and dimensionality of random light are important concepts in modern optical physics and photonics. Methods: By use of space-frequency domain coherence theory, we establish a rigorous classification for the electricfield vector to oscillate in one, two, or three spatial dimensions. Results: We also introduce a new measure, the polarimetric dimension, t...

The process of edge electrospinning relies on forming electricfield-induced instabilities (i.e., jets) in a polymer solution bath which act as sources for nanofiber production. As such, it depends on the fundamental interactions between the fluid and the electric field, which are studied in this report as a function of solution parameters (viscosity, surface tension, and conductivity). Over a w...

A hole spin is a potential solid-state q-bit, that may be more robust against nuclear spin induced dephasing than an electron spin. Here we propose and demonstrate the sequential preparation, control and detection of a single hole spin trapped on a self-assembled InGaAs/GaAs quantum dot. The dot is embedded in a photodiode structure under an applied electric-field. Fast, triggered, initializati...

Two stationary, partially polarized electromagnetic beams with equal degrees of polarization may exhibit completely different time evolutions of the instantaneous polarization state. In this work, we derive a statistical quantity that describes the rate at which the field intensity in the beam, on average, is redistributed between the beam’s polarization state at any time and the state orthogon...

Bismuth ferrite, BiFeO3, is an important multiferroic material that has attracted remarkable attention for potential applications in functional devices. While thin films of BiFeO3 are attractive for applications in nanoelectronics, bulk polycrystalline BiFeO3 has great potential as a lead-free and/or high-temperature actuator material. However, the actuation mechanisms in bulk BiFeO3 are still ...

A plasma that is confined in a closed field line geometry such as a levitated dipole may be subject to the formation of convective cells. Using a “Drift” fluid model we show that such flow patterns can represent an appropriate equilibrium in a dipole field that contains a plasma with a non-axisymmetric pressure profile. This can provide a means of fueling and heating a dipole confinement device...

In this study, the relationship between auroral absorption, electrojet currents, and ionospheric plasma convection velocity is investigated using a series of new methods where temporal correlations are calculated and analysed for different events and MLT sectors. We employ cosmic noise absorption (CNA) observations obtained by the Imaging Riometer for Ionospheric Studies (IRIS) system in Kilpis...
