Spin and orbital-to-charge conversion in noncentrosymmetric materials: Hall versus Rashba-Edelstein effects
Diego Garcia Ovalle, Aurelien Manchon
We investigate spin- and orbital-to-charge conversion phenomena in nonmagnetic materials with broken inversion symmetry, treating the contributions from the Hall effect and the Ras…

Moiré amplification of highly tunable shift current response in twisted trilayer graphene
Yuncheng Mao, Claudio Attaccalite, Diego GarcÃa Ovalle
In this work we analyze the shift current conductivity in helical twisted trilayer graphene. Without loss of generality, we show that the density of states and the twist angle set…

Orbital Kerr effect and terahertz detection via the nonlinear Hall effect
Diego Garcia Ovalle, Armando Pezo, Aurélien Manchon
We investigate the optical response induced by a d.c. current flowing in a nonmagnetic material that lacks inversion symmetry. In this class of materials, the flowing current exper…
