Novel effects and quantum platforms for spinorbitronics and superconducting spintronics

This talk will deal with the presentation of quantum materials platforms with potential impact in the area of spinorbitronics and superconducting spintronics which combine spin-orbit coupling, superconductivity and topological effects. We have theoretically considered the interplay between geometric curvature effects [1] on the electronic properties and the topological features of the quantum states in low-dimensional nanomaterials. I will discuss how geometric effects in low-dimensional nanomaterials can lead to a metal-insulator transition and promote the generation of topological states of matter [2]. For instance, upon the application of a rotating magnetic field one can realize the topological pumping protocol in an entirely novel fashion [3]. Further, I will present the intricate twist between spin texture and spin transport in shape-deformed nanostructures, including the superconducting case [4,5]. Finally, within the superconducting spintronics framework, I will provide basic views of the way how spin-triplet pairing is modified at the interface with magnetic systems and consider the interplay of superconductivity and magnetism in heterostructures with a special focus on topological superconductors [6-10].
