Role of the magnetospheric and ionospheric currents in the generation of the equatorial scintillations during geomagnetic storms [PDF]
The equatorial ionosphere parameters, Kp, Dst, AU and AL indices characterized contribution of different magnetospheric and ionospheric currents to the H-component of geomagnetic field are examined to test the geomagnetic activity effect on the ...

Decay of superfluid currents in the interacting one-dimensional Bose gas [PDF]
We examine the superfluid properties of a 1D Bose gas in a ring trap based on the model of Lieb and Liniger. While the 1D Bose gas has nonclassical rotational inertia and exhibits quantization of velocities, the metastability of currents depends ...

A quantitative model of the magnetosphere with poloidal vector fields [PDF]
A quantitative model of the magnetospheric magnetic field is developed using poloidal vector fields. This formalism is applied to the ring current region, the distant field and the return currents.

Basic image and dynamic variation processes of planetary ring currents
Ring currents, an important current system formed by the azimuthal drift of charged particles in planetary magnetospheres, play a key role in disturbing planetary magnetic fields and driving magnetospheric dynamics.

Persistent current in isolated mesoscopic rings
Persistant current in isolated mesoscopic rings is studied using the continium and tight-binding models of independent electrons. The calculation is performed with disorder and also at finite temperature. In the absence of disorder and at zero temperature agreement is obtained with earlier results by D. Loss et.

Light-induced valley currents and magnetization in graphene rings
We study the non-equilibrium dynamics in a mesoscopic graphene ring excited by picoseconds shaped electromagnetic pulses. We predict an ultrafast buildup of charge polarization, currents and orbital magnetization.

Filtering of spin currents based on ballistic ring [PDF]
Quantum interference effects in rings provide suitable means for controlling spin at mesoscopic scales. Here we apply such a control mechanism to the spin-dependent transport in a ballistic quasi one dimensional ring patterned in two dimensional electron
