Engineering topological states, spin textures and spin interferometers by shape deformations — •Carmine Ortix — Institute for Theoretical Physics, Utrecht University, Princetonplein 5, 3584 CC Utrecht, Netherlands

I will discuss the possible interplay between curvature effects on the electronic properties and the topological properties of the quantum states in low-dimensional nanomaterials. In particular, I will present the intricate twist between spin textures and spin transport in shape deformed nanostructures. Non-uniform Rashba spin-orbit coupling in shape deformed quantum rings leads to spin textures with a tunable topological character. These topologically non trivial spin patterns affect the electron spin interference, thereby resulting in different geometry-driven electronic transport behavior
