Phase-space jets drive transport and anomalous resistivity

Berry-phase effect in anomalous thermoelectric transport.

We develop a theory of the Berry-phase effect in anomalous transport in ferromagnets driven by statistical forces such as the gradient of temperature or chemical potential. Here a charge Hall current arises from the Berry-phase correction to the orbital magnetization rather than from the anomalous velocity, which does not exist in the absence of a mechanical force. A finite-temperature formula ...

Anomalous Resistivity in the Auroral Plasma

One of the key problems to the understanding of auroral arcs is the resistivity that they present to the flow of fieldaligned electric currents. Since collisional resistivity cannot account for the observations, one is faced with the question of what kind of collisionless process can account for the enhanced resistance. Previous theories [Kindel and Kennel, 1971] attempted to associate the anom...

High Energy Jets in the Earth’s Magnetosheath: Implications for Plasma Dynamics and Anomalous Transport

593 The region downstream of a supercritical collisionless shock, the magnetosheath (MSH), is known to be in a highly disturbed turbulent state [1–3]. The undisturbed solar wind (SW) streams with supermagnetosonic velocity V > c ms at a magnetosonic Mach number up to M ms ~ 15. At the Earth’s bow shock (BS), the SW decelerates to Mach numbers M ms < 1, thermalizes, and, when entering the MSH, i...
