Abstract: In this talk, the nature of single electron states and the corresponding quantum transport properties in certain low dimensional tight-binding model systems will be discussed. Real space renormalization group (RSRG) decimation technique and the transfer matrix method (TMM) have been employed to bring out some interesting localization-delocalization features of electronic states in such simple model systems with quasiperiodic and fractal geometries. The idea of spin transport and spin filters for higher order spin states in addition to the spin 1/2 case in model magnetic chain systems will also be addressed.
