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…
Novel topological insulators from crystalline symmetries
Alexander Lau, Carmine Ortix
We discuss recent advances in the study of topological insulators protected by spatial symmetries by reviewing three representative, theoretical examples. In three dimensions, thes…
Spin interference effects in Rashba quantum rings
Carmine Ortix
Quantum interference effects in rings provide suitable means to control spins at the mesoscopic scale. In this chapter we present the theory underlying spin-induced modulations of…
Spin field-effect transistor in a quantum spin-Hall device
R. Battilomo, N. Scopigno, C. Ortix
We discuss the transport properties of a quantum spin-Hall insulator with sizable Rashba spin-orbit coupling in a disk geometry. The presence of topologically protected helical edg…
Inversion-symmetry protected chiral hinge states in stacks of doped quantum Hall layers
Sander H. Kooi, Guido van Miert, Carmine Ortix
We prove the existence of higher-order topological insulators with protected chiral hinge modes in quasi-two-dimensional systems made out of coupled layers stacked in an inversion-…
Higher-order topological insulators protected by inversion and rotoinversion symmetries
Guido van Miert, Carmine Ortix
We prove the existence of higher-order topological insulators in: {\it i}) fourfold rotoinversion invariant bulk crystals, and {\it ii}) inversion-symmetric systems with or without…
