We investigate the transport properties of an interacting ring threaded by a magnetic flux and with Rashba spin-orbit coupling, based on a recently developed functional renormalized group technique. In the calculations of the electronic transport processes, the Coloumb On-site interactions are taken into account. For an interacting ring connected to two leads, we find that (i) for ΦAC = 0, the behavior of transmission zero at ΦAB = π is generic for the universal regime; (ii) for certain ΦAC and ΦAB, one can use the mesoscopic ring as spin filter even in the presence of the local interaction in the ring.

Effect Of Disorder

ABSTRACTAll organic photoreceptors are now widely deployed in electrophotographic copiers and printers and represent the most important and commercially successful application of electronic organic materials. The need to optimize polymers for this application has stimulated fundamental investigations of charge generation, injection and transport processes in the disordered organic solid state. Electronic transport in a wide variety of glassy polymeric insulators has been studied by the time of flight drift mobility technique. It is typically found to proceed by a field driven chain of thermally activated tunneling events among active, compositionally identical, but energetically inequivalent sites. The inequivalece of site energies is attributed to the combined effect of disorder and site relaxation. Polymeric systems which differ widely in composition and morphology are found to exhibit a remarkably recurrent pattern of features in their transport behavior. Theoretical attempts to account for these universal features have been frustrated by their inability to explain the sublinear field dependence of the drift mobility and its variation with temperature. The drift mobility of polymers can be systematically modified by doping. Doping studies have provided the design rules which enable the fabrication of trap free polymers. The latter are an absolute requirement in electrophotography.

F Ring

ABSTRACTSaturn's broad E ring, the narrow G ring and the structured and apparently time variable F ring(s), contain many micron and sub-micron sized particles, which make up the “visible” component. These rings (or ring systems) are in direct contact with magnetospheric plasma. Fluctuations in the plasma density and/or mean energy, due to magnetospheric and solar wind processes, may induce stochastic charge variations on the dust particles, which in turn lead to an orbit perturbation and spatial diffusion. It is suggested that the extent of the E ring and the braided, kinky structure of certain portions of the F rings as well as possible time variations are a result of plasma induced electromagnetic perturbations and drag forces. The G ring, in this scenario, requires some form of shepherding and should be akin to the F ring in structure. Sputtering of micron-sized dust particles in the E ring by magnetospheric ions yields lifetimes of 102to 104years. This effect as well as the plasma induced transport processes require an active source for the E ring, probably Enceladus.
