Physics We calculate energy dispersion relations, transport properties, and the effects of magnetism in three condensed matter systems. Specifically, we investigate the effects of placing chains of metallic particles in an anisotropic medium and in the presence of an external magnetic field. Specifically, we calculate the effects of these perturbations on the energy dispersion relations of the plasmons that propagate along chains of metallic particles. Next, we investigate the effects of adsorbed atoms on graphene. We find that in low concentrations these additional atoms change the density of states and create a magnetic moment that can be tuned with an appropriate external potential. Finally, we investigate the combined effects of a temperature gradient and external magnetic field on the transport properties of the semiconductor InSb. We find that the transport properties, and specifically the spin-dependent Seebeck coefficient, oscillate as a function of magnetic field as the Fermi energy crosses the Landau band minima. We also suggest that by including spin-orbit interactions in the Hamiltonian we can calculate the magnetic field dependence transverse Seebeck effect in an electron doped semiconductor such as InSb. 2015-05-14 English text The Ohio State University / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=osu1417604062 http://rave.ohiolink.edu/etdc/view?acc_num=osu1417604062 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
