Temperature scaling of effective polaron mobility in energetically disordered media

Abstract Armco 18 SR is a ferritic stainless steel that provides excellent resistance to high temperature scaling. It is readily welded by conventional methods and is not subject to troublesome embrittlement or loss of corrosion resistance in the heat-affected zones that affect many other straight chromium alloys. This datasheet provides information on composition, physical properties, hardness, and tensile properties. It also includes information on high temperature performance and corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: SS-259. Producer or source: Armco Steel Corporation, Advanced Materials Division.

Abstract UNILOY 430 is a medium-chromium (17%) non-hardening, ferritic stainless steel. Of the AISI 400 series stainless steels, Uniloy 430 most nearly resembles the 18% chromium-8% nickel stainless steels in fabrication and service. It has excellent resistance to corrosion and good resistance to elevated-temperature scaling. Its many uses include architectural trim, nitric acid storage tanks and kitchen appliances. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties as well as fracture toughness and creep. It also includes information on high temperature performance and corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: SS-408. Producer or source: Cyclops.

The study of transport phenomena in disordered media is a subject of wide interdisciplinary concern, with many applications in fluid mechanics, condensed matter, life and environmental sciences as well. Flows through grossly irregular (porous) media is a specific fluid mechanical application of great practical value in applied science and engineering. It is arguably also one of the applications of choice of the LBE methods. The dual field–particle character of LBE shines brightly here: the particle-like nature of LBE (populations move along straight particle trajectories) permits a transparent treatment of grossly irregular geometries in terms of elementary mechanical events, such as mirror and bounce-back reflections. These assets were quickly recognized by researchers in the field, and still make of LBE (and eventually LGCA) an excellent numerical tool for flows in porous media, as it shall be discussed in this Chapter.

Localization Behavior

AbstractIt has been shown recently that the backscattering of wave propagation in one-dimensional disordered media can be entirely suppressed for normal incidence by adding sample-specific gain and loss components to the medium. Here, we study the Anderson localization behaviors of electromagnetic waves in such gain-loss balanced random non-Hermitian systems when the waves are obliquely incident on the random media. We also study the case of normal incidence when the sample-specific gain-loss profile is slightly altered so that the Anderson localization occurs. Our results show that the Anderson localization in the non-Hermitian system behaves differently from random Hermitian systems in which the backscattering is suppressed.
