| Details: | Deterministic fractal geometries have beautiful self-similar patterns and they provide us with the fractional dimensions. Investigating the nature of single electron states and their transport properties in these fractal lattices is an intriguing question. In this talk, first I will discuss examples of fractal lattice geometries where we can specify how single electron states will be localized or extended in such fractal space. Then I will show examples where we can engineer interesting flat band states in such fractal-like geometries and also in some other regular lattice geometries. Finally, I would like to discuss a few results from my work on spin transport and spin filtering effects in simple magnetic chain models. |
