Spin Hall and Edelstein effects in a ballistic quantum dot with Rashba spin-orbit coupling
Alfonso Maiellaro, Francesco Romeo, Mattia Trama +11
We study spin-resolved transport in a ballistic quantum dot with Rashba spin-orbit coupling, focusing on charge-to-spin conversion and spin Hall effect. In the regime where the dot…
Stability of graphene hyperbolic pseudospheres under harsh conditions
T. P. C. Klaver, R. Gabbrielli, V. Tynianska +2
We demonstrate the high stability of simulated graphene hyperbolic pseudospheres under large externally imposed deformations and high temperature annealing. Hyperbolic pseudosphere…
Theory of charge-to-spin conversion under quantum confinement
Alfonso Maiellaro, Francesco Romeo, Mattia Trama +6
The interplay between spin and charge degrees of freedom in low-dimensional systems is a cornerstone of modern spintronics, where achieving all-electrical control of spin currents…
Tunneling current and current correlations for anyonic quasiparticles of ν = 1/2 chiral Luttinger liquid in multi-edge geometries
Gu Zhang, Domenico Giuliano, Igor V. Gornyi +1
We consider anyonic quasiparticles with charge e/2 described by the ν = 1/2 chiral Luttinger liquid, which collide in a Hong-Ou-Mandel-like interferometer. These colliding anyonic…
Spin-dependent gap in graphene on a magnetic substrate
P. M. Sheverdyaeva, G. Bihlmayer, E. Cappelluti +12
We present a detailed analysis of the electronic properties of graphene/Eu/Ni(111). By using angle and spin-resolved photoemission spectroscopy and ab initio calculations, we show…
Interfaces of nodal-line semimetals: drum states, transport and refraction
Mattia Rudi, Alessandro De Martino, Kristof Moors +2
We study transport through interfaces in topological nodal-line semimetals, focusing on two geometries: a single interface between two large samples, one nodal-line semimetal and o…
