Electronic materials with nanoscale curved geometries
Paola Gentile, Mario Cuoco, Oleksii M. Volkov +4
Research into electronic nanomaterials has recently seen a growing focus into the synthesis of structures with unconventional curved geometries including bent wires in planar syste…
Spin-Orbital Textures and Interferometers by Nanoscale Geometric Design of Quantum Rings with Orbital Rashba Coupling
G. Francica, P. Gentile, M. Cuoco
We derive an effective continuum model for describing the propagation of electrons in ballistic one-dimensional curved nanostructure which are marked by a strong interplay of spin-…
Magnetic field effects on electron transport in nanoring with orbital Rashba coupling
Gianluca Francica, Paola Gentile, Mario Cuoco
We study the effects of a Zeeman magnetic field on the electron transport of one-dimensional quantum rings which are marked by electronic states with orbital symmetry in the pr…
Engineering Topological Nodal Line Semimetals in Rashba Spin-Orbit Coupled Atomic Chains
Paola Gentile, Vittorio Benvenuto, Carmine Ortix +2
We study an atomic chain in the presence of modulated charge potential and modulated Rashba spin-orbit coupling (RSOC) of equal period. We show that for commensurate periodicities…
Geometric driving of two-level quantum systems
Zu-Jian Ying, Paola Gentile, José Pablo Baltanàs +3
We investigate a class of cyclic evolutions for %the cyclic evolution of driven two-level quantum systems (effective spin-1/2) with a particular focus on the geometric characterist…
Effects of geometry on spin-orbit Kramers states in semiconducting nanorings
G. Francica, P. Gentile, M. Cuoco
The holonomic manipulation of spin-orbital degenerate states, encoded in the Kramers doublet of narrow semiconducting channels with spin-orbit interaction, is shown to be intimatel…
Independent geometrical control of spin and charge resistances in curved spintronics
Kumar Sourav Das, Denys Makarov, Paola Gentile +4
Spintronic devices operating with pure spin currents represent a new paradigm in nanoelectronics, with higher energy efficiency and lower dissipation as compared to charge currents…
A topological quantum pump in serpentine-shaped semiconducting narrow channels
Sudhakar Pandey, Niccolo' Scopigno, Paola Gentile +2
We propose and analyze theoretically a one-dimensional solid-state electronic setup that operates as a topological charge pump in the complete absence of superimposed oscillating l…
Designing Electron Spin Textures and Spin Interferometers by Shape Deformations
Zu-Jian Ying, Paola Gentile, Carmine Ortix +1
We demonstrate that the spin orientation of an electron propagating in a one-dimensional nanostructure with Rashba spin-orbit (SO) coupling can be manipulated on demand by changing…
Edge states and topological insulating phases generated by curving a nanowire with Rashba spin-orbit coupling
Paola Gentile, Mario Cuoco, Carmine Ortix
We prove that curvature effects in low-dimensional nanomaterials can promote the generation of topological states of matter by considering the paradigmatic example of quantum wires…

Paola Gentile, Mario Cuoco, Carmine Ortix
We derive the effective dimensionally reduced Schrödinger equation with spin-orbit interaction in low-dimensional electronic strain driven nanostructures. A method of adiabatic sep…
